Thought it would be great to have ways of stealing technology... or maybe share technology... would bring co-op play to a whole new level...
Think about a TEC players buildnig Vasari ships (not all of them or anything like that) but stealing the tech to build just one thing or something like that.
or maybe spys could disable another player's research so that a technology is nolonger available to them... like erased from their systems or something...
