C.3 Giving Each User a Separate Machine (Colocation)

A much better and simpler (but costly) solution is colocation. Let the users hook their (or your) standalone machines into your network, and forget about the issues raised in the previously suggested setups. Of course, either the users or you will have to undertake all the system administration. Many ISPs make sure only that the machine is up and running and delegate the rest of the system-administration chores to their users.
