2) Decipher still owns the RPG system. We COULD swipe most of it, provided that we omitted Trek specific terms and some game specific terminology.
They don't own the system, just the presentation and trademark. It's very possible to redo a 'Coda SRD' so long as it doesn't infringe on either. Heck, at this point, it may be worth the time to SECURE the rights outright (and I may call on that).
But the real question might be, "Why switch?" We already got the books, and no one is going to be bothered by our using an RPG that we already own. Now that DECTrek is defunct, we can probably pick up back up copies fairly cheap on-line.
Largely for bringing in other players to play too.. hard to get new guys into the fold if the material isn't available.
