Yes, you can. Check this out..bluCTRL wireless Bluetooth keyboard and mouse It's still in beta so it's free too and I have not noticed any bugs. Also makes your BB a wireless mouse.
Not made for the storm, and the "Remote" screen doesn't seem to work for me unless I assign the commands to a character on the storm portrait keyboard, but it works... and fairly well at that.
Ok, not quite the same thing, but I did find a free app for Mac OS X that lets you control Powerpoint, iTunes, and other apps via the Apple Remote. This remote comes with all Macs / Macbooks equipped with a IR receiver.
