Be aware that GIO/GVFS are very high level. In other words, they work
for the Gnome guys because they don't realise that not all the world
links to libgnome ;-)

zip and tar and rsync and amanda won't work with them. Any modern
program will break trying to use a GIO/GVFS "mount" as their location
of storage. Moderately modern interfaces like mmap - that you need to
work on advanced filehandling, for example in image manipulation
programs - don't work either.

I expect GVFS to work well for file copy, move and for basic file
viewers, not for a real read/write application.

Hmmm. See my notes here in a somewhat similar discussion -

Look at git-fuse.

I think git fuse also has similar ideas.
