I love reading stuff like this - really useful. Every time I try to use D2W I get a certain distance into it and then feel as as if I'd be faster developing a standard WO app than navigating a whole new manner of thinking (and composing rules). Figuring out how to make a D2W app flexible has been hard for me to wrap my head around.
Thanks for the great ideas!
