Because of the way animals work in pre release (and proberly in 1.0) maby we could buy animals from votepoints.
Ofc It would also be nice if you could only kill agressive mobs on lots you are not a member on, to avoid people killing your farms (that way we do not have to have huge walls around ouer farms making them look worse than needed.
It all depends on how the game handles logging out, if friendly mobs despawn when no player is near then it dosnt matter. Havnt had a chance to test 1.0 out in that reguard maby someone know?
