Sounds cool. You can do most of that with APT today by the way (the
dojo widget part would have to be a custom handler though) without
having to use S2 (not that using S2 is a bad thing!). I suppose I
should feel some sense of validation that the basic idea I presented 2+
years ago for S1 now makes it, roughly, into S2 :)
