Ooohh!  That is interesting.  I especially like that it could remove
the reliance on layer 2 and VLAN switching.

I think this would mean we'd have to by default, route an entire
subnet to either quarantine and individual /32's to unquar or vice
versa.  This might not be that big of a deal, but it I guess I'd
have to think this through a bit more to see what kinds of issues
this invokes.  In addition, that means we'd have to re-design the
Netpass system, but it sure sounds easier to do that than having
to program layer 2 switches.
