It's not so nice, in the sense that there is a fair amount (~1400
lines) of support code, but I've got a library that makes it quite
nice from the filesystem writer's point of view.
For example, mounting an ftp server takes ~180 lines of code. A test
filesystem is <60 lines...
BTW: all the code is Python (for better, for worse!), and it does NOT
pretend to be an NFS server (yuk!). However, and this is a hint(!),
the kernel agent is in the standard Linux distribution, and has been
for years! It is also in several other OS distributions, but I haven't
tried my library on them yet. Any guesses?
I keep meaning to package it up, and release it - if there is any interest...

Here, here!
