As per the title, how moddable will the various factions be?  Will faction traits like free culture generation and multiple starbases in a gravity well be moddable?  Will Rebels and Loyalists share PlayerXXX.entity files and ship and structure lists?  Will Rebels and Loyalist tech trees be split up in the code so modders can give Rebels and Loyalists radically different tech trees, and not just a few different options to each?  Will modders be able to add new races complete with their own Rebel/Loyalist splits and unique faction traits?

I hope someone from Stardock or Ironclad can answer my questions.
