Bah! If the user checks a box saying the network can be trusted then we
should use that as evidence against him. :) Firewalls are "crunchy on
the outside but chewy on the inside". How many of our users have a
not-fully-patched Windows box on their "trusted" home network? (Or even
an active malware infestation.)

And what if you and a friend are at the airport and you want to share a
file? Do you have to mark the airport wifi network trusted?

It seems like it would be better to use selinux here than a firewall.
