    Let's think about turning that around a little...it'll allow you to
turn off the PC's so they can get reset every night and cause less
problems.  :)

    Make a share on the Linux server, and 'export' it.  At night it can
be backedup every night, allowing you to save the tapes of the backups
every night.

    The user's view would be an icon that, when they click on it will
take them to their own directory which will actually live there, not
locally. (This can also be used to keep viruses from wiping out the
whole thing...allowing harm only to the user's files...something to
think about.

    Yeah, creating "CDs" on the server saves time, too. Good Man.

    Actually, you're better off with diskless clients...think about it:
you'll NEVER have to obsolete them. You'll never have to remove viruses
or referee an argument because someone's computer's too loud.

    And the only time you'll EVER have to replace it is when someone
takes a sledgehammer to it, or the roof falls in.  It's not a bad
trade-off: now you have machines to make DNS/Web/LDAP servers with.  :)
