A loosely-coupled low-security auth scheme for controlling access to public
LAN's -- I want to allow other people to use my LAN if they can present a
valid ticket, but I was under the impression that true cross-realm auth was
a bit too closely knit for this purpose. A simple conf file statement like
# these realms I trust to use my net:
An user with a valid ticket in these realms would get access, to the LAN
and routing beyond, but no other resources.
But I suppose shortcuts in system design are the mother of all evil..
