I think you are introducing a new different concept here, something that I
would call an 'Editor'.
Thus, we will be talking about a 'Data/View/Editor' model.

I'm interested. I've used that model at some extent and I'd like to go
further with it.
BTW, which should we use as a reflector? Perhaps this discussion list.
Note: I'm currently trying to finish a late project,but I am supposed to be
finishing it next week or so; after that I'm in.
