Hi George,

Likely couldn't travel that path; each new provider that accepts the
more specifics into his routing table only increases the percentage
penetration. Catch ditch the tunnel JV until you have nearly 100%
penetration and the cost of carrying all the routes in every router
versus a fraction of just the small routes in each of the JV's routers
is high enough to cost more than the small users are willing to pay.

You could, however, implement a dynamic tunnel map-encap protocol like
they've been discussing over in the RRG for the last couple of years
and let the ASes start to deploy ingress tunnel routers to catch
otherwise-unrouted packets for the /8 near their source and send them
encapsulated to their current destinations. Many outcomes are
possible; I'm not really looking to explore the whole field.

My point was that I'd really like to see us stop suffering failures of
imagination in the name of careful reason. ARIN has to be the
moderating force on the routing table only because we've failed to
imagine a individually driven process that renders the role
