Uhm, who contractually disallows that?  I.e. if I have provider A space and
a provider B connection in addition to my provider A connection, both would
have to announce the block which provider A allocated to me, specifically,
or it would be /impossible/ to use both lines at the same time.

You're taking full routes aren't you? :)  (I'm not at the moment, or I
would do it.  There are a few other things I want to do with a BGP dump
anyway).  If anyone is willing to make a dump available to me for ftp I
would be greatly appreciative.

Having been involved in all of the discussions at Erol's as to their
renumbering plan (they are renumbering out of their original PA space at
the moment), the one thing that is a real nightmare for ISPs to renumber is
name servers.  I really do not envy their position in telling 200k users to
go into their settings and change their DNS server IP's.
