Hmmm.. maybe we need WebDAV support?

Maybe an RMI lookup mechanism would be more appropriate. IE the ability
to serve up a java.io.File. This would be a *very* tight mapping :).
The only problem here is again... how do we resolve URLs to files?.. in
a reliable manner.

I would say WebDAV or RMI. RMI would probably be easier to implement
and more reliable but has the drawback that we need to use the Servlet
API to resolve URIs.
