I'm not supposed to say this, but you guys are the best
Nothing's official yet, but a friend of mine was interested in this nickname project. We've discussed it a bit, and the best way would be for WMPlus to have an extra interface which applications can use to query it for media information. This enables his application to watch for changes and automatically update your nickname. Once this is working and stable I'll write some documentation so anyone is able to use the WMPlus "engine"...
Best of both worlds, I don't have to spend my time on features I don't like, and you get a nickname changer
