Excellent! At first I actually wanted to change mc-vfs to be able to
work standalone, but found it too daunting task. Now I see Pavel
Machek is workin on this full steam, brave man ;).

I would gladly contribute, but I have no internet (i.e. CVS) access,
only Web access. Are there tarball snapshots available? Best would be
if the VFS part could be downloaded separately (since it's now
standalone).

Yes I was. Now I'm trying to make it work using the LD_PRELOAD dinamic
linking mechanism (see zlibc) of redefining the open, etc. syscall
functions. This way programs don't need to be changed or recompiled at
all! Some success (e.g. Emacs is now working perfectly with AVFS), but
a lot of thing to sort out yet...
