Correct. However, if everyone did that, we would quickly have collisions
among the 1,000 or so available private ASNs. I do not think pTLAs have
a srong interest in maintaining a list of private ASNs they peer with.

Nice try, no cigar.

I think they do.

In the 6bone context, I do not see a problem with that, but it does not
scale at all. If BGP is to be used in any form or fashion for IPv6
multihoming, we will soon need 32-bit ASNs.
