Topic: A Windows program that controls the Chumby...
I made a little program to control the Chumby from a Windows box in case anyone's interested:
Scroll down to "ChumbyRemote".
The gist is it will make your Chumby play various internet radio stations, and you can set the volume, both from Windows.
Note that you need to set the IP address of your Chumby in configuration.ini, which by default lives at c:\program files\ChumbyRemote\configuration.ini, and you need to enable SSH on your Chumby, deets on how to do that are at that link above.
And it's sloooow, like up to 3 seconds before the Chumby reacts. But it generally works.
