If you can raise enough funds, you can also try doing gear "draft" systems. Buy a ton of completely random magic gear from the AH or from donations.
Before the game starts, you dump piles and piles of blue items onto the ground. When the competitors enter, they each go one at a time and select one item on the ground (10-15 seconds time limit, perhaps), constantly rotating until they're all fully geared.
Damnit, this is why the 4-player limit per game is so absolutely lame.
