I like this idea. There is only one problem that I see with it. The as numbers in as-in and as-out lines are often used (by tools like prpath and prtraceroute) to deduce the topology of the Internet. If an AS only specifies a policy like:

aut-num: AS2 as-in: from (NOT AS1) 5 accept ANY

then prpath has no way of deducing the neighbors of AS2.

Doesn't that deduction belong in the inet-rtr ifaddr and peer lines?

aut-num: AS2 neighbor-list: AS3, AS4, AS5, AS1 # pehaps with router addresses?

This is reasonable for AS that don't provide inet-rtr records for their routers (I suspect most). Curtis
