Is there a Zune development kit? That would rock! I don't own a Zune yet, but want one. I think a Zune SDK would be really neat. Does Zune run on the .NET Compact Framework?

I think two things that would be really awesome would be an SDK, and compatability with the XNA framework. My vision would be to use the wireless networking capabilities to be able to play multiplayer games where you can import music from your player to be the background music of the game.

From what I've seen of the Zune it could be pretty awesome, but I have heard the UI for the desktop app is pretty "lacking"
