Using autofs to mount user dirs...

    We're in the process of separating some of our services off of one 
server and onto others.  At the moment we have one server that houses 
everything for our users.  I'd like to move everyone's web space onto 
our dedicated farm, but leave the user login on the current machine.  
And the idea is that I would use netfs to auto mount their webspace 
either when they login to their account, or just when they actually need 
to access it.

    My problem is that I'm not sure netfs can actually do this without 
me having to have each and every user listed in an auto.X file.  User 
web folders are in /home/$USER/www and on the remote server they will 
live in /mnt/ext/www/$USER

    So how do I configure a netfs map file to do this, if it's even 
possible?  All the examples I've seen are for maps where the entire path 
is known (and fixed).  Here my $USER is a variable...
