{looks at Stars! and MOO2 for inspiration}
Hyper-Expansionists - Gets a modified colony ship hull that can carry 7 engines (fastest thing in space!), and cheaper colony components; enhanced population growth facilities (like Organic)
Stealth Masters - alternate cloaking devices which cost less research and resources; stealth armor that provides level 2 and 3 cloaking; modified base hulls with level 1 built-in Active-EM cloak
Warlords - muchos advanced weapons and big ships!!!

also a maintenance reducing facility like the Crystalline Restructuring Plant, and training facilities... this one should be expensive! (since I combined Stars! "War Mongers" with MOO2's "Warlord")
Inner Strength - better armor, shields, repair, minesweepers
Space Demolitionists - hyper-advanced mines & warheads; mines get built-in long range scanners/anticloak scanners
Interstellar Traveller - cheaper open/close warp points components; open/close warp points facilities (if such things are possible); enhanced supply components & cheaper resupply depots
Space Miners - greatly enhanced remote mining (such that it's more profitable to remote mine than to mine normally)
Master Spies - better intel facilities/ops, small ships get built-in scanner and/or cloak
Ramscoop Engines - can build Ramscoop engines, which move very slow but use no supply
Recyclers - gets advanced recycling facilities right off the bat
Alchemists - gets resource converters right off the bat
Bleeding Edge Technology - would require duplicates of ALL other techs, but it would be cool - new techs initially cost double, but they
improve faster
Cybernetic � Better repair components; healing armor
