I'm using Keyclone now, and have been for about a year.
The product is relatively easy to set up, I was confused for a little bit, but there are video's right on his site www.solidice.net/keyclone

As far as keyboard clicks go, the program is extremely good.
The mouse broadcasting is not totally precise, but its close enough for things like Huricane or Force of Nature.
Lately I've been looking at IS Boxer and IS Toolkit, both for the ease of FTL set up and the Mouse Broadcasting.
Still using Keyclone, functionally it does everything I need.
Just I really like some of the things I'm seeing Zanthor do in his assorted threads.
