Thanks a lot, that was extremely helpful. I now have a simple version of the program working, and I'm getting ready to start writing the http-parsing code that will give me things like the currently playing artist, song, album art, etc. Is there a way I could get you to add in queries that will return something more easy to parse? Perhaps something like JSON, or even a simpler HTML page with the data tagged in some way?
Other than that, I've got most of the functionality I'd like with just the commands and the status - I'm basically re-writing the Pandora client UI as a C# app that suits the Pocket PC interface better. I suppose I could just use the webpage, but that'd require you to do work, which doesn't seem fair. Unless you want to give me access to the source... but I can understand not wanting to do that.
