there is also a program called remote buddy that will let you map the apple remote to any application.
you can also use a wii-mote which connects via bluetooth, so you don't have to point directly at the mac. plus if you have a sensor bar (basically a couple of infra-red LED's) you can use the wiimote as a mouse, and it come with a built in mouse highlight option, so you could use it as a pointer.
Thanks, everyone. I should've just googled it I guess, but I got the problem solved anyway. Now I can go buy one! And haha I like the letmegooglethatforyou thing, very funny.
