Version: (using KDE KDE 3.5.7) Installed from: Ubuntu Packages amarok supports DAAP, which can only be used to connect to iTunes. Furthermore is DAAP no open protocol. UPnP is open and is already used by a lot of Hardware and Software. There are UPnP clients and servers for Linux. I would really like to see amarok support UPnP, as a client would be great, as a server even better.
Currently no one is willing to implement this... so if you're willing to do it ;-)
I'm working on it. Have a dev-sprint this weekend in fact.
This is currently subject of a GSoC project, expect some news this fall.
Implemented in today's git, will be shipped with Amarok 2.4
