I was looking into this exact same thing. Only I wanted to do it with nostromo n52s (much harder). I never got to the actual testing of it, but it should be possible.

At this point I am waiting for the USB multiplexer to be released.


The reason keystroke broadcasters are not "the best" solution is they can lag. It might not be an issue with WoW, but I play EQ2 which LOVEs to eat up as much of the CPU as it can, this seems to bottleneck slower PCs and will cause a large amount of lag in the keystrokes.
