[Loser]

I believe that putting a damage value for ranges all the way up to 21 will make a missle keep going until it hits its target, but I haven't tried that.

Neutral races can only have technologies available to everyone else, and only get unmodified racial charactaristics, I believe.

However, you can make interesting non-neutral AIs that will stay in their system by only supplying ship designs that will not explore, like defensive ships. They will only leave their homesystems if they are given system maps of other systems, as non-exploring ships will not corss warp points that lead to the unknown. I don't immidiately recall all the specifics of this 'bottled demon' style AI, but it has been discussed somewhere.
