I found the following Channel 9 videos which might be interesting for you while searching for a Bluetooth remote control application sample :)

Building a Mobile Service:

While we were at the Topcoder contest last month handing out Nine Guys we met Alex Kipman (he is lead program manager on MS Build). He has a cool demo of using Visual Studio to build a system for a variety of mobile devices.

Of course the demo was done in a hotel lobby of a Silicon Valley hotel. Hear the kids screaming. Heheh.

Anyway, learn how to use Visual Studio to create a system that'll call MapPoint that'll use a GPS and a variety of mobile devices.

Look at Bluetooth Programming on Windows Mobile

Anil Dhawan, a Program Manager in the Windows Mobile group, provides a look at Bluetooth programming on Windows Mobile devices and shows remote control of PowerPoint from a Smartphone using Bluetooth. Mike Hall is the interviewer and camera guy.

Building Your Own Home Server

Chris Gray, a developer in the Windows Server team shows how to use managed code running on a Windows Mobile device to upload photo's from a Pocket PC to a home server - the demo shows the back end 'server' code and the code running on the device.
