Suggestion for stirring up trouble:
Launch drones at some AI you don't have a treaty with, and you can't afford to get into a war with, but is causing you problems (putting colonies in a system where you don't want them?)... Then go to diplomacy screen and GIVE the drones to another AI before they hit.

Since drones cannot be reprogrammed after launch you've done some damage to your enemy and 'framed' the other AI. Does it work?

If it does, it's nearly as much fun as the telepathic trick in MOO II where you take a colony & give it to another AI before the fleet arrives to take it back. Instant war between two AIs.
