MVVM Silverlight

So this topic has been going around for some time about building MVVM Implmentations in Silverlight a couple of people I know are doing toolkits (surprise surprise WPF guys mostly) but here are two of my favorites include Michaels:

and Laurents:

any real dive into the topic should also include shawn's blog/posts starting with say this one http://wildermuth.com/2009/06/10/DevTeach_Silverlight_MVVM=Easy_Demo

In any case since I've been focusing on the composite apps as of late I'm going to work on something based on Michaels and get that posted.
