tfrangoullides, Girder pro is possible to use directly with tcp/ip. Search the forum and you will find some posts about it. One can control most of the things on a pc with girder, for example change resolution, start program, hibernate or restart PC etc. I use it to control MediaPortal, wake/hibernate PC:s.

Try also to google for a solution for tcp/ip and WMC, I think that someone made a server program for this and you can download it for free. Haven't tried it myself.
