The best stuff on this ... by FAR .. on big-time UI patterns can be found in a series of articles by Martin Fowler that is supposed to go into a book but doesn't seem to be coming soon. It's on the web, though, and nothing else comes close in both ease of understanding and explanatory power.
You should know that we will be retiring Funhouse in favor of Cabana. MS CAB (on which Cabana rests) is the future of composite UI architectures. Funhouse was pretty well aligned vis-a-vis MVC and MVP but it is a far cry from what CAB can do.
I know it may seem scary ... we are just gathering our materials on Cabana ... but if you're considering this kind of thing, I recommend that you take a breath, relax, and dig in.
We'll be coming to press with more explanatory material in the coming months.
