Mouse broadcasting in OSX?

I'm an old hardware multiboxer trying to get back into the game and was looking at the USB broadcasters from Vetra. I sent them an email back on 6/28 asking about their 5+ port USB broadcasters and availability but hadn't hear back. Anyone around here know of another option for broadcasting mice?

I've considered the various software options, but I'm a mac user with a stack of 5 mac minis and would rather not have to reboot into windows each time I want to play wow (partially because my iTunes server runs from one of them and my wife would get annoyed not being able to watch itunes content that's not streamable from them).

If anyone has any solutions for mouse broadcasting in OSX I'd be open to hardware or software solutions. I actually have keyboard working with an old PS/2 KVM broadcaster, but the mouse doesn't seem to work with macs. I've been trying to find some unencrypted wireless mice to just do the one mouse/multiple receivers option but all modern mice I can find will only connect to one receiver. Thanks for any suggestions!

I do not know of any mouse broadcasters for OS X.

synergy may be able to do it, but it would probably require some code tweaking. You could try googling synergy broadcast and see what turns up.
