I am using Kavoom with no major issues. It is active at windows login so I can login all the pc's from one keyboard. It transfered all my keyboard commands (so far) with no issues. This includes the G15 and Xkeys.

The only issue I have seen is trapping the focus on another pc because of network tie ups. I.E. wow is loading from the file server or if I mess up keyclone. In these situations I just wait or kill the offending app and control with be restored. But these limitations are user imposed and not the fault of the software.
