The thing I wanted was to start off everyone with all the colonization techs. This gets rid of the temptation to swindle the AI for its colony tech and lets you expand faster (both you and AI).

Check out the Colony Tech Mod by Ekolis, which adds 3 "native" racial traits that give access to the appropriate colony modules. It makes it so that it is impossible to trade starting colony techs (which are by no means "technology"...). You can still research others, and you can trade researched colony techs with other races that share your homeworld type (such as rock races trading ice and gas), but not with races from other types of planets. The methodology for a gas race to colonize an ice world would be vastly different than a rock race colonizing an ice world, for example. Very little could be shared between them.
