Been dual boxing for a while with Multplicity (Use synergy at work but mouse spins on gaming).

I just purchased a Logitech G15 and was wondering if it is possible to send the extra G keys to my other system only. I have been reading that multibox can do selective key broadcasting on the modified version but the link won't work to test it out. Is there anybody who has this working or any other options that would work. I will probably still use Multiplicity as from reading about synergy it will only work with standard keys. I was just hoping to set these extra buttons to control my second box.

Any info would be appreciated.
