Have you heard about Salling Clicker? It used to be an OS-X-only application to remotely control your Mac via a PDA or cell phone (certain types, not all PDAs or phones are supported, but they have a pretty comprehensive list) over Bluetooth. When I tried out this program about a year ago I used it to control my Mac mini with my Tapwave Zodiac 2 and my Sony Ericsson T610. It not only controls iTunes, but also can control other programs like your e-mail client and iPhoto, for instance. It’s also scriptable so that you can essentially program it to control whatever program you want. I haven’t actually tried the Windows version, but I know that even today it has been extended to control Front Row in OS X. Pretty cool remote control program. I’m not sure, but it might also work over WiFi now.

I should really play around with it again now that I’m exclusively using a Tablet PC. See how the Windows version works.
