ISP A has thousands of customers. ISP B also has thousands of customers.

ISP A has peering established at a dozen public peering points but 
wishes to give that up in favor of buying transit.

ISP B wants to have peering at a dozen public peering points with those 
same peers and knows that their network footprint and traffic mix is 
sufficient to keep all or nearly all of those peers comfortable with 
simply continuing the peering arrangement with their entity. (Rather 
than the contractually safer, and 8.2-compilant process, but extra cost 
and overhead of having to move the peering agreements and the contracts 
into a subsidiary that one then sells via the M&A transfer process).

So ISP B buys from ISP A the AS number, the right to use the circuits, 
and maybe some rack space. And possibly a few of the border routers. 
Nothing more.

Shouldn't that transfer be able to happen under 8.3?
