Others use tunnels, PPPoE or lots of scripting, so certainly something
can be done about it.  To my knowledge, SAVI SEND is still at a
similar stage.  Pointers to vendor documentation would be appreciated
if this is not the case.

And SAVI SEND is not the full story---it's still missing unicast flood
protection.
