here is an example of the kind of draft I might hope 6man discussed. If you want, we can hack this into a better input to them.

A previous answer to James, with an extract below, is I believe also relevant.
You write in your draft "The most general case, that of assigning subnet numbers throughout an arbitrary complex topology, may be beyond algorithmic description." The SAM approach may not be intended to deal with the "most general" case, but it deals already deals with a "quite general" case: multi- layer hierarchies, multihoming possible at each layer, flexible numbers of bits used at each layer. 
It is also expected to remain simple and incrementally deployable.

Discussing it in Stockholm would IMHO be useful.

Careful with that axe... if we're going to require prefix sub- delegation in best-practice CPE routers, then I contend we absolutely need to specify how that's done with zero configuration. 

Agreed
Are we ready to do that yet? I don't believe we are. Very happy to be proven wrong about that. 

Agreed that we are not ready yet.
To make progress, my work on SAM (draft-despres-sam-03) includes an attempt at providing a solution. The approach will be presented at the Intarea session, Wednesday 15:10-16:10. The ID abstract says "... Global prefixes delegated by a zone to its child interfaces can be obtained by autoconfiguration, thanks to to a bidirectional correspondence between SAM local addresses and SAM global prefixes..."
