No, that's an argument for a /32 and a bunch of /48 allocations heard by a single provider, who's getting paid to carry them, but are not advertised to the rest of the Internet. > And they may use different carriers in different > cities.

Well, wait a minute - what would these people do TODAY? Some build tunnel backbones, some use one ASN per city, some do "allowas-in" or other things of that nature. I would venture to say that most medium to large enterprises don't use straight-Internet with no VPN of any kind to support their enterprise backbones anymore, simply for security reasons. My argument still stands - if having an ASN is equated with having a routable netblock, then each of those cases results in the enterprise being able to pass packets, and only the "one ASN per city" approach requires multiple netblocks. -David David Barak Need Geek Rock?
