Control iTunes from network

[sharkkk]

Is there an elegant way to control iTunes on a Win7 machine (which acts as a home server) from another Win7 on the network?

Alternatively/Also, is there a nice way for network users to be able to choose a local media file and have it added to the server playlist - so network users can choose their own files or files from the server to play, and the server will play them iTunes-DJ-stylee?

Thanks for any help!

iTunes isn't required, it's just good at handling large libraries and the users are familiar with it!
WMP is not so elegant And I don't know of a way to start playing a file on another machine with it?
