Valdis, Your message is generally well put. However, while it is possible to send the packets on the wire, the fundamental underlying scaling point, the routing system, has not been properly addressed. Perhaps a solution can be retrofitted in, but then again, who knows? This, I thought, was <largely> the point of multi6. Eliot
