Keyclone and Synergy integration? (mac and pc usage)

I'm just starting out my multibox planning and want to take advantage of some existing hardware I have. I'm looking for advice on how to setup an environment where I have one Mac laptop (a Macbook Pro) and one WIndows PC (4 GB Ram, good processor, etc).

My goal is to run one toon on the Mac, and four toons on the PC. Can I run Synergy on the Mac and have it send keystrokes to the PC and have Keyclone broadcast the keystrokes to each one of the Wow apps? (I can't test it myself without buying a copy of Keyclone.)

If this won't work, then the Mac laptop to PC really has me stumped.

Any advice appreciated! Thanks.
