mac mouse broadcasting... is it out there?

hey ive been a guest/fan to these forums for a while, and because i always seemed to find my answers quickly, i never needed to post anything. but for some reason i cant find any information on this here or anywhere... but i still have hope.

is there any sort of mouse broadcasting for mac os? i know i can partition and play in vista for one of the many options, but with something like bootcamp, windows, 3x wow, + extra software... dunno if this would be wroth it. plus dont have the funds for that sort of thing atm.

thanks for any info
