Much of which I stole and stuck into
http://www.aminus.org/rbre/shoji/shoji-draft-01.txt, which is being used
to run http://parachutes.org/api/browser for one. Why not push ahead
with that? Given the dearth of complexity in implementations of URI
Templates, I'd much prefer the simpler syntax you proposed there. Make
it simple enough, and regexes for dispatching on the server fall out
quite nicely.
