An interesting variation here would be to move home directories
and authentication to a central machine and add a server or
two to the backbone network but continue to use classroom servers
wherever you have a concentration of clients and a convenient
location to park the local server and switch.  In this scenario
the local servers can all be clones with no individual configuration
required so you eliminate local maintenance and if you have some
spare capacity on the backbone servers you could just change
the local switch connection to use them if a local server fails.

That seems like a safer way to go if you already have some
number of classroom servers.
