for a while we had this kind of set-up with Ubuntu netbooks. Following
some difficulties with samba, I ended up mounting tjener homes via
sshfs. I placed a shortcut on the desktop which ran a script asking
for username and pw and doing the mount. Since these were shared
laptops, I created a regular user and applied some edubuntu lockdown
techniques (pessulus and something else) before cloning. Two problems
occurred - 1. kids managed to customise things despite the locking
down and 2. if someone saved a file into the tjener mount point
directory, but had forgotten to mount, then no-one could mount their
home on that laptop anymore.
You might get what you want from autofs, ( I couldn't understand it
enough, so if you do, please share!)
As far as infrastructure scaling goes, I can't help. We are a very small school.
