And where will the static files go?  You want the rule to be that some 
URI prefixes are for static files, and everything else belongs to the app?

At least it sounds now like there is no deep problem with FastCGI 
support in Ur/Web, where the worst known problem is forcing inclusion of 
a URI prefix unique to the application.  There are also the wishlist 
items about easier deployment including static files, and I'd still love 
to read some suggestions on that subject.  As far as I understand, 
Ur/Web isn't any worse off there than mainstream frameworks, and it 
seems plausible to me that some deployment system can be built as an 
external tool.  For instance, I use Autoconf for that purpose in one 
closed-source project, where a .ur file is written containing the needed 
information on URL generation.

Works, thanks.  Just pushed it.
