My current loot management setup:

Free for all, main picks up all loot. Main has a macro set up on the key that the slaves all use for their follow macro.

Code:
/script AcceptTrade()
/script InitiateTrade("target")
All the slaves have an extra line in their follow macro:

"/script AcceptTrade()"

That way, I don't use an extra key for passing around loot. :thumbsup:
