The idea of putting "vfs" in the path name is not good, IMO. The _whole_ purpose of 
"userspace filesystems" is to be fully transparent for apps, and
"vfs/protocol/server/path" is hardly "transparent". The whole point of a userspace
filesystem is having a "~/music", "/randomstuff/" or whatever without caring about
what program is behind or who is providing it.

What we have now is:
kernel-libc <-> "path name" <-> apps

What people here is suggesting is:
kernel-libc <-> "path name" <-> apps
						    |---> additional layer

And the Right Way (TM) of doing it is:
kernel-libc <-> "path name" <-> apps
                      |---> userspace filesystems

IOW: apps get the cool stuff without knowing it.
I mean, people is suggesting to create this standard, and then if an app wants to be aware
of the functionality provided by this standard we need to modifiy _every_ app on the planet,
from gnome/kde to apache. Path name involves everybody, not just desktop.

What's so bad about doing a _good_ design and implement this behind apps, so they
don't need to know anything at all about files being implemented by kernel or userspace
programs? Creating a alternative vfs different from the real one, which needs to be
implemented by every app is a quite ugly design, as far as I can see....
