I wrote a user-mode filesystem for Linux just yesterday. In Python
(using a library I hacked up early last year). Works great. One of these days
I'll get around to packaging it up, and releasing it, if people are
interested.

bash$ wc -l ftpfs.py testfs.py
    171 ftpfs.py
     46 testfs.py
(the library is a little bigger! :-)

BTW: it doesn't use FUSE (or NFS - yucky yuk!, or even samba - yes
that's been done too!) - just standard Linux kernel modules...

However, ideally, I would prefer to be using Ron's v9fs with namespaces!

PS, my list of user-mode filesystem projects is:
	avfs/fuse: http://sourceforge.net/projects/avf/
	userfs: http://www.penguin.cz/~jim/userfs/
	uvfs: http://www.sciencething.org/geekthings/index.html
	Podfuk: http://atrey.karlin.mff.cuni.cz/~pavel/podfuk/podfuk.html
	lufs: http://lufs.sourceforge.net/lufs/
	virtualfs: http://www.solucorp.qc.ca/virtualfs/

	(although the last subverts libc, rather than using a kernel module)
