I just finished GMing a game of star trek themed diplomacy. The idea is that seven major alpha-quadrant (also gamma and beta) powers are fighting over europe. Each of them gets powers that are kind of like their star trek powers. For example, units defeated by the borg are assimilated instead of dislodged, and the federation player my designate one unit as the Enterprise, which will successfully complete it's mission even against impossible odds. The variant was designed by Michael Harvath and the original rules are on the variant bank as "Star Trek Civilization Diplomacy (st02)". We made some changes to the rules to address possibly paradoxes and other things that we were not clear about. We've put them online.

Because there were special rules and secret information, diplomacy programs like realpolitik were not up to the task. Instead I wrote a minimal python program to deal with who-knows-what and drawing the map. This is online as diplomator, the only diplomacy program capable of mapping the alpha quadrant. If anyone else wants to use it, you might want to ask me for pointers; it's very nice when you know what you're doing, but it's not entirely obvious how to use it.
