Does this mean that you support 2005-1, or do you think a new ARIN proposal is needed ?

I think that is overly pessimistic.  I would say that SHIM6 _MAY_
become a routing trick, but, so far, SHIM6 is a still-born piece
of overly complicated vaporware of minimal operational value, if any.
Personally, I think a better solution is to stop overloading IDR
meaning onto IP addresses and use ASNs for IDR and prefixes for
intradomain routing only.
Full ACK! For the IDR we then can use perfect match lookups which
scale very well and pretty cheaply to many millions of table entries.
BGP scales very well too if you've got a decent cpu in your router.
Our OpenBGPD easily does 30 flapping constandly full-feeds with 1 million
routes each.

Lets get pragmatic and realistic!
