Topic: remote control with cog only ?

is there a way to disable my remote control with itunes and quicktime and get it to work with cog only ?
because if i have itunes or quicktime running and i'm listening to music with cog and i press play on the remote control it will react on both cog and itunes/qt
i need it to work with cog only
if i pair my remote with another mac, will it work or will it disable it completely ?
