I use a mixture of PC's and Mac's. I use Apple Remote Desktop for the Mac's and RealVNC for the PC's. I use HotKeyNet for my key broadcasting. It works. No problems. Okay, I can't figure out how to send ALT key reliably, but I just use SHIFT and CTRL instead. I would like a complete solution, but most broadcasting programmers don't seem to want to cross platform boundaries. Until they make a wireless X-Keys, this will have to do.
