in theory it'd be possible to write an app that interacts with it by sending applescript commands, but i don't know if anyone is actually attempting this

but you could in theory skin a program that's just a gui front end to itunes and simple sends whatever clicks and commands it receives over to IT to play
I hacked together a php script when i was at uni that had a basic html form with buttons to play, pause, prev, next, volume etc... i used my mobile to access it over wap and control itunes from around our house (well usually just from my bed:)... i had an applescript running on my mac that just grabbed an XML value every few seconds (from the PHP script) which corresponded to the command i'd pressed on the form.
It all worked quite smoothly when it was running, just had a delay of a few seconds. But yeah, it's possible to put an HTML interface on it, would work well if it was all local.
