Mongoose's 2d6 OGL deserves a Microlight version along similar lines to what Greywulf has done for the D20 OGL. The idea is to create a very minimalist set of rules using the OGL alone (not the TLL), which would still work quite well with existing adventures and settings.
What I'm thinking about is:
Stats and Skills:
Three Stats: Strength (STR), Dexterity (DEX) and Mind (MIND). Stats generated by rolling 2d6 three times and assigning as the player wants (this is OGL alone, not TLL, so I can tell you how to generate stats).
Stat DMs are (Stat-7)/2 , rounded down.
In addition, roll 2d6 for your Endurance Pool (END). It is not used in task resolution unlike the usual stats, but instead represents your body's ability to withstand abuse. Damage is always taken off your END first. As long as your END is above zero, you aren't wounded in any serious way, but rather bruised, fatigued, scratched etc. Once your END reaches zero damage applies to STR or DEX (defender's choice).
Six Skills: Physical, Technical, Stealth, Knowledge, Space and Social.
You should be able to simulate any OGL skill by a combination of a 2d6 Microlight stat and skill. For example, Gun Combat would be DEX+Physical (or DEX+Technical for complex vehicle weapons, or MIND+Space for ship gunnery); Melee would be STR+Physical; Science would be MIND+Knowledge; Engineering (or Computer) would be MIND+Technical; Mechanic would be DEX+Technical; Leadership would be MIND+Social; Pilot would be DEX+Space; Vacc Suit would be STR+Space; Medic would be DEX+Technical for first aid, MIND+Technical for high-tech medical care, and MIND+Knowledge for complex diagnosis; Recon would be MIND+Stealth; Stealth would be DEX+Stealth; Drive would be DEX+Technical and so on.
CharGen
At the most basic level all characters should be assumed to be 30 years old and after three terms of service. Career should determine your starting skills:
Marines: Physical 2, Technical 1, Stealth 0, Knowledge 0, Space 1 and Social 0.
Navy: Physical 0, Technical 2, Stealth 0, Knowledge 0, Space 2 and Social 0.
Army: Physical 2, Technical 2, Stealth 0, Knowledge 0, Space 0 and Social 0.
Scouts: Physical 1, Technical 1, Stealth 1, Knowledge 0, Space 1 and Social 0.
Merchants: Physical 0, Technical 1, Stealth 0, Knowledge 0, Space 1 and Social 2.
Noble: Physical 1, Technical 0, Stealth 0, Knowledge 1, Space 0 and Social 2.
Rogue: Physical 0, Technical 1, Stealth 2, Knowledge 0, Space 0 and Social 1.
Scholar: Physical 0, Technical 2, Stealth 0, Knowledge 2, Space 0 and Social 0.
Belter: Physical 1, Technical 1, Stealth 0, Knowledge 0, Space 2 and Social 0.
Agent: Physical 1, Technical 0, Stealth 2, Knowledge 0, Space 0 and Social 1.
Additionally, each character would have an Expertise - a specific field in which he'll have an additional +1 DM. For example, a character might be a Pilot - and would have a +1 DM when piloting things, but not for other Space or Technical rolls. Or a Doctor would have a +1 DM for medical purposes - but not for other Technical rolls. As a rule, Expertise fields should always be significantly narrower than standard Microlight 2d6 skills.
Each character gets 2d6x1,000 Credits in starting funds, but could only buy up to Cr2,000 worth of gear prior to actual play. A ship (or vehicles or other gear more expensive than Cr12,000) is assigned to the group if the referee deems it fitting; otherwise she might decide that they'll have to work hard to get a ship.
Tasks
Task Resolution is 2d6 + Stat DM + Skill + Difficulty DM. A roll of 8 or more is a success. The roll's result minus 8 is the Effect. If desired, roll 1d6 for Timing.
Easy tasks have a DM of +4.
Routine tasks have a difficulty DM of +2.
Average tasks have a difficulty DM of +0.
Difficult tasks have a difficulty DM of –2.
Very difficult tasks have a DM of –4.
Formidable tasks have a difficulty DM of –6.
Combat
There is no initiative - everything happens simultaneously, and the results of combat actions (e.g. wounds) are applied AFTER all combat actions are resolved.
Ranged attacks are DEX+Physical.
Melee or Thrown attacks are STR+Physical.
Vehicle Gunnery attacks are DEX+Technical.
Damage is by weapon, with the attack's Effect added to it. Armor is subtracted from the damage.
When using automatic fire, roll a number of dice equal to the Auto rating of the weapon and sort them into pairs as you wish. Each pair is an attack. Auto-fire attacks can be allocated to any target within six meters of each other. Auto-fire attacks cannot benefit from a skill any higher than level 1. Auto-fire in SMGs and rifles uses up half the clip; autofire in machine guns uses one tenth of the ammo belt.

Vehicles in Combat
Vehicles have three possible kinds of armor: Light ("soft-skinned" civilian vehicles), Medium (ATVs and light APCs) and Heavy (heavy APCs and tanks). Similarly, in regard to their ability to damage vehicles, all weapons are split into three groups: Small-Arms (pistols, rifles and light machineguns), Support (heavier machine guns, man-portable lasers, hand/launcher grenades) and Heavy (rocket-launchers, rocket-propelled grenades, heavier vehicle lasers, PGMPs, FGMPs, light artillery). When you hit a vehicle, don't roll damage; instead, consult the following table:
	
	
	
		
If the damage is External, roll once on the External Damage Table below; if the damage is Internal x2, roll once on the Internal Damage table below; if the damage is Internal, roll twice on the Internal Damage table below; And Destroyed means that the vehicle is completely destroyed.
An attack with an Effect of 4 or more moves one column to the right. For example, a small-arm attacking a lightly-armored vehicle would cause two rolls on the Internal table. You can't cause more damage than Destroyed, but Internal x2 becomes Destroyed and Internal becomes Internal x2. Heavy Artillery always destroys all player-scale vehicles.
The damage table is:
	
	
	
		
Internal Roll: Roll once on the Internal table.
Sensors: Sensors blinded.
Drive: Vehicle immobilized, but easily repaired.
Weapon: One weapon is disabled.
Lights: The vehicle's external lights are destroyed.
Absorbed: The damage is absorbed by the vehicle's armor with no significant adverse effect.
Breach: If the vehicle is pressurized, the pressure seal is broken. If it is not pressurized, ignore. All Internal hits cause a Breach in addition to their usual damage.
Destroyed: The vehicle is destroyed, everyone in it takes 4d6 damage.
Power Plant: Vehicle disabled.
Life Support: The vehicle's life support system is disabled.
Cargo: One important piece of cargo (chosen by the Referee) is destroyed.
Passengers: One passenger is hit with the weapon's full damage.
Fuel: Causes a fuel leak, mobilizing the vehicle after 1d6 turns. Further hits are ignored, unless the munition is explosive; in such a case, the vehicle catches fire.
Computer: Computer systems disabled.
Cockpit: Pilot/Driver takes the weapon's full damage.
