a techology i think is missing form traveller? integrated networking.
You're kidding, right? Just because there aren't PC-level rules for networking between ships you seriously think it isn't happening? There aren't rules for shoe salesmen and plumbers so they can't exist either, right?
using Interferometry techniques, you could gain an effective sensor apature with a diamiter of thousands of KM. that would give you pin point targetting info for things like Meson guns.
What makes you think that meson guns aren't targeted that way already? You're talking about an emitter aboard a vessel traveling along a varying high speed vector successfully targeting another vessel which is traveling along a varying different high speed vector at range measured in light seconds. Meson guns aboard ships are able to aim so precisely that the particles decay INSIDE the target.
Have you also forgotten that a moving ship can employ interferometry too? If the time lag inherent in passing sensor pictures between separated ships can be adjusted for, the time lag in taking sensor pictures at different times from the same moving ship can be adjusted for.
it would make Picket screens significantly more effective, as it would give them access to very high resolution sensors.
There are lots pickets, escorts, and other ships in the setting. They seem to be of little use in a Book 5 battle between battleships, so what do you think they're doing there? Might their role in providing sensor information be something that occurs in the setting but wasn't included in the game because it would increase complexity and slow down play without providing a worthwhile benefit?
A supposed lack in rules doesn't mean a lack in reality.
Never heard of Virus?
If you want to avoid Virus, there are also references to cyberattacks assisting hijackers from CT through Hard Times. The game already has rules for computers, intrusion, electronics, comm operations, and other so why should anyone need specific cyberpunk rules?
I feel obliged to note that nanoscopic, self repicating objects with no objective other than making more of themselves already exist. thier called Viruses, and while nasty, have not wiped out all life on earth.
I'd be obliged if you understood how virii worked. They need a specific protected environment in which to "work" and that "work" can be easily stopped. The same is true of the nano we use today.
We're using nanotech right now. Your printer uses a nano produced product, so does your sunblock, and the uses are growing. What we aren't using and can never use is Drexler's version of nano. It's a thermodynamic impossibility.
