This is a step in the right direction, but before anyone wastes more time
working on a completely unportable solution (with minimal chances of ever
making it into the kernel), please have a look at

specifically at hlfsd (home-link filesystem daemon). It implements exactly
what you want, through a user-space nfs daemon, is portable and keeps
unnecessary stuff out of the kernel.


  It is better to keep your mouth shut and be thought a fool,
            than to open it and remove all doubt.
