Anyone know of a Mac solution for mouse broadcasting?

[NewbieMultiBoxer]

I've searched everywhere and can't find anything that can do it! The only thing that comes close is Synergy with Broadcasting, but that variation of Synergy seems to have fallen off the face of the internet as I can't seem to locate it anywhere. Does anyone else know where I can get it or possibly know of an alternative solution for an intra-system multi-application mouse broadcaster/duplicator?

Not exactly a Mac solution, but its an option if you want to use the best boxing software.
