Ok, so I need to write out the rootURL to be able to read it back in.

When I originally prototype the vfs code, I did start out with URI. The problem was that you always had to go to the URL in order to get the io streams, or come up with another URI handler framework. Its a decision we need to make.

Yes, we would need a mapping in context factory to avoid explosion of vfs contexts on deserialization.

No problem with that.
