Not sure if you aware but there is an IETF Internet Draft winging its way through the system on this topic, namely http://www.ietf.org/internet-drafts/draft-michaelson-4byte-as-representation.... txt It did get discussed on the IETF idr list in October 2006, and met significant resistance. There were also comments then about NANOG taking a position on this. I haven't seen any discussion since.

Folks,
One of the items that was discussed during the working group meeting in Amsterdam was the relative benefits of using asplain, asdot or asdot+ to represent four byte autonomous system numbers. The chairs feel that the discussion tended towards favouring asdot/asdot+, which is already used relatively widely, but with the note that people do need to review their in-house tools and scripts to ensure they will work with numbers expressed in this notation.
Cheers, Rob
