Part of the problem here is network design. For example, if when laptops are
brought in they were only allowed to connect to a wireless network and that
wireless network was on the far side of the firewall (perhaps slightly more
access than from the internet but still majorly firewalled) and treated as
untrusted systems which they in fact are, then it would not be such an
issue.

There is no rule that says you can't have internal firewalls to separate
untrusted from trusted systems. But you have to design your network around
this idea for it to work.
