>Has anyone using MM separated the UI into View and ViewModel in the MVVM model? CSLA's video by Lhotka on this suggests that when additional frameworks are present which already separate out the Biz/DAL tier that the VM can be significantly leaner than traditional MVVM.

I don't have an entire clean grasp of the construction needed in MVVM but I am working on it diligently now. The main issue will be keeping a very clean View Model without duplicating the work already in the Business layer. Currently the UI gets it's data through the Business object and so the binding isn't quite right for MVVM pattern. It will be interesting to figure this out and I will keep you posted if you keep me posted on any progress or things you learn.
