[Slick]

I hope it works well with game mechanics. It sounds like it might be difficult to implement:

- empires A, B & C join an alliance
- empire A proposes to attack empire D
- empire B agrees, but empire C disagrees and offers a counter-proposal
- empire A & B agree
- alliance moves fleets toward empire D
- meanwhile empire E has declared war on the alliance
- *sigh, politics... here we go again...*

each of these would take at least 1 turn during a multiplayer game (unless communication (via email or equivalent) outside the game is allowed)
