Hi Bo,
There are a number of music sources supported on the Chumby already; when you get one you can see how they’ve implemented them, at least from a user interface standpoint. There’s obviously a lot of different levels for “support” of the Chumby and we could talk about them.
The board doesn’t allow me to send you a PM so, please drop me an email, wjm (at) wjm.org and we’ll talk some about it.
Bill
