reiser4 has prompted the discussion again, but it doesn't provide the
virtual filesystem capabilities that we're talking about, which Gnome
and KDE implement in userspace.  The FUSE project is much more
relevant for that.

We had file-as-directory discussions years ago, and 5 years ago I was
experimenting with doing virtual filesystems with that capability over NFS.

podfuk offered something close to Gnome and KDE but in kernel space:
virtual filesytems accessible through the kernel, but it didn't get
too popular.  It was based on Midnight Commander's VFS (which has
evolved into Gnome's VFS), using the CODA filesystem interface to
provide the kernel hooks.  It had some problems, and was a bit fiddly
to use.  We still don't have something that's particularly nice to use
for ordinary users.
