Much as I'd like to take the credit, it was Duncan Coutts who implemented that 
feature :)

That would certainly be neat.  Maybe it could be implemented in Haskell using 
YHC's JavaScript backend?  (half-joking...)

can view it with file:// URLs.  Maybe there's a way around this though, I'm not 
an AJAX expert.
