msn messenger and media player plugins - similar plugins that desktop sidebar has

I have just switched from using Desktop Sidebar to truelaunch bar. however there are some features that desktop sidebar had that I sure wish truelaunch bar has. It has a way to monitor the online status of your microsoft instant messenger buddies aswell it has a better windows media player control function. the reason that i switched from desktop sidebar is that it was a resource hog. they didn't build it smart.

Is there any future for plugins in these areas?
