Pocket PC Remote for Windows Media Center
Darius Wey over at Pocket PC Thoughts wrote a remote control app for Windows Media Center. Using his plug-in for Media Center, in combination with software running on a Pocket PC, you can control playback of your media remotely. The app supports useful features like text entry where sending IM messages to friends might be cumbersome in using a Media Center remote. PPC Tablet is required for core remote control functionality.
