Ah, I've always wanted to play Traveler. I started working on a space-faring game myself, but lost the time to other projects. I did make a new old-school fantasy rpg a few years ago, though. It's called Wayfarers. My nome de plume is Swill.
Some day, I want to release another edition of the game as a tablet app.
Firefly was so much like my Traveller campaign that I suspect that Joss Whedon used to play it.
