Best Silverlight Ribbon and Docking Implmenetation
I'm in love with DiveElements' SandDock and SandRibbon.

Unfortunately, I can't bundle these in an open-source project.

Can anyone suggest the best open-source Silverlight ribbon and docking implementations please? 

For docking, I'd like it to be like VS, being able to pin and move panels around in various layouts.
