We could have an api that lets you map a URI into a vfs object with a
more complicated API that lets the application have a dialog with the
user requesting things like authentication and prefered filename
encoding for the share (essentially a mount operation based on a uri).
We would need to use something like that anyway in the file selector,
because it would need to be able to mount things as you input locations.

On the other hand, exposing URIs like that in the API will be tricky for
other implementations of the vfs. For instance, on windows we probably
wouldn't be using the gnome implementation of the vfs, but rather
something using the native vfs, including the built in smb support, etc.
And win32 doesn't use URIs for this.

One approach could be to have backend specific APIs one could use for

How would you like it to work? I can't believe you actually like the
current way this work, with authentication callbacks, etc.
