Sorry... I was talking about Eds proposal... I hadn't noticed the shift
to an entirely different proposal by John.

I think Eds proposal (which I proposed some modification to) has merit.
I think Johns alternative is far less desirable and agree with your concerns
about it.

The proposal wasn't for "parallel" ASN space.  The proposal was to have
a range of ASNs for leaf-networks and a range for transit networks,
allowing transit networks to make more rational (possibly automated)
decisions about route aggregation.

That may be sane, but that's not how I read John's actual proposal:

Along these lines, one could leave the transit AS networks alone if a
parallel 16 bit ASN space were created. Essentially, any non-transit
network would have it's non-public ASN retranslated NAT-style by
upstream  transit network border routers. Only the border routers would
have to be  changed. They would have to differentiate between public ASN
X and  non-public ASN X (same number) based on the which side of the
router the  ASN was learned from.

I don't see anything about ranges, but an entire parallel 16 bit space.
And John's definitely talking about them possibly having a 1312 on both
sides, because it matters which side you hear about it from.

Conversely, if it matters which side you hear about it from, it also
matters which side you announce it on.. which was my point.
