I may have misread your post, but it seems to me like you have a fundamental misunderstanding of the ViewModel and Model portions. Yes, your View should only bind to stuff in the ViewModel only. However, the ViewModel is not creating, copying, storing, loading, saving, etc. the data, that is the models job. The ViewModel is simply a thin *wrapper* around the model and has a reference to it. If your model is implemented correctly, you shouldn't need much (if any) repackaging of the data. Your ViewModel generally just exposes a bunch of RelayCommands that manipulate the model. If you are doing a lot of repacking work in the ViewModel, or are copying around data a lot... as they say on teh internetz: "UR DOIN IT WRONG!" Smile | :)
