Its just exploratory for now to see if I can even come up with a reasonable strategy for possibly moving to the MVC model in the long run. While it seems very daunting at first look I have some ideas about a strategy that I want to at least evaluate.
Since I am going to re-write SiteOffice using YUI anyway, I may try to do that using MVC. I may also consider re-doing just the site admin pages in MVC.
Nothing is really decided and I would not expect to see rapid progress in this direction but I am attracted to the MVC way of doing things so I needed to create the mvc project to have a way to explore it further as time permits.
