I've been doing some research, and changing the nickname in Messenger 6 is not nice. It involves opening the options screen and all, and even though I would probably be able to do it whilst keeping it hidden (got some hooking experience
) I don't think I'll try that at first...
However! I did have another idea, which I think is even better. Display Pictures. I just did some tests, and thanks to the interface Plus! provides (wasn't able to do it with an external application) I can set the display picture to anything I want. Combined with song-change-monitoring and some graphics skills, it's possible to have the current song displayed as a display picture. Of course that would involve some skin settings to customize it
. I was also thinking about an option to show the WMPlus DP (display picture) for an x number of seconds, then revert back to the old, though I haven't experimented with going back yet. Either way, I've Paintshopped a small example of what it could look like. Even the shadow of the text is easily done... in fact, I might even implement monitoring code for Winamp and Sonique as well, polling every 5 seconds isn't that bad and DP changes take some time transferring to contacts anyways...

Oh, and of course the Play button would change into a Pause button when the player is paused, etc
. Just a general background change in such cases, so anything is possible...
