I suppose that if you find a set of companies that are all willing to be part of the consortium & just part of the consortium, then you could do addressing for this consortium as a whole. Hey! I think that we just invented provider (consortium) based addressing again.
One can also play tricks with tunnels, so that the folk with long prefixes inside the consortium's aggregate can get to the consortium without anything else needing to know a route for the long prefix. The packets travel farther (from source to consortium, and then from consortium to destination via the tunnel), but that's OK, because both the destination and the consortium are paying. --apb (Alan Barrett)
