Hello, all...
I was a Beta. I helped T5 along best I could. Heck, my name is even on the title page. Alas, I can't comment on playability because I have no one to play with. Much sadness.
Just wanted to put that out there...

I can recommend for you roll20.net . This seems custom-made for sad, isolated players. It is a shared tabletop system for gamers to meet, teleconference and get chat, sound and even video for each player. The GM of course has more controlling power over this tabletop, can design maps and store handouts, and many varieties of dice can be rolled (by anyone). It is
free to join, but GMs can pay an annual subscription to get extra features on their tabletop that their players can see.
I like the "token" system where you can create a token for a player, move it around the map, and link it to their character sheet numbers, and a pop-up menu on each token features numbers to count things like hit-points, status markers, etc. What is changed on the token is also changed on the sheet, which is a great convenience.
This is also
compatible with Google+ Hangouts. It can be implemented to play boardgames and card games too, but imaging individual game components may take some time!

Since I joined in early summer, subscribers jumped from 155,000 to 220,000. It may not be a total substitute in-person RPGing, but it does seem to assemble all the elements in front of you and your players.
One problem is that the game-search feature needs work; I'm not sure I'm seeing all the possible campaigns going on. But if you pick your keyword by game system it should tell you everything for your interests. It is majority D&D and Pathfinder members so far, but we can change all of that, and spread the word about SF games, can't we?
