I've found some strange things using the anagram server at
http://www.wordsmith.org/anagram/advanced.html. Entering key FreeSpace terms/words/names gives back some strange results. A copy of my findings are below.
Note: These results are obtained with the candidate word list filter set to "Yes"
Asterisked results are detailed afterward.
SPECIES:
Terran = RANTER
Shivan = VANISH*
Ancient = CANINE*
FACTIONS:
Neo-Terran Front = TERROR
Galactic Terran-Vasudan Alliance = UNCERTAINTIES*
Parliamentary Vasudan Empire = UNIVERSALITY, and my personal favorite, PREMENSTRUAL
Galactic Terran Alliance = INCARCERATING
Galactic Terran Intelligence = TRICENTENNIAL
Special Operations Command = DISAPPEARANCES
SHIPS:
Sathanas = SATAN
Demon = NODE
Rakshasa = SHARKS
Colossus = SOULS
Enif Station = INFESTATION
SYSTEMS:

Epsilon Pegasi = ESPIONAGE, PIPELINES
Gamma Draconis = COMMANDS, or my personal favorite, ORGASMIC

Eltanin (alternate name for Gamma Draconis) = ALIEN

OTHER TERMS:

Beta Aquilae Convention = BICENTENNIAL*
Subspace = CAUSES, or ABUSES

That's all I found of interest. Feel free to look at that site and see what there is to see. Some special things I noticed;
Shivan-Vanish: May have something to do with a) how the Shivans quickly disappear after their attacks, or b) how many civilizations (Ancients, for example) vanished entirely.
Ancients-Canine: Could relate to the physiology of the Ancients and their technology?
GTVA-Uncertainties: Could relate to possible struggles within the GTVA?
Ross 128-SOS: Could relate to first encounter with Shivans?
BETAC-Bicentennial: Could relate to revision/revocation time?
ETAK-Take man in: Could relate to Bosch's mission with the ETAK project?
It took me about 3 hours to compile this, so I hope it stirs up some questions. Thanks for reading this!
