Russ,

If you read the SKIP draft, you will realize why interactivley negotiating 
SAIDs is not a good idea, when one is not interactively negotiating
keys.

Actually, there was some verbal agreement at the last WG to use
4 bits of the SAID for the IPSP protocol version number, and
the remaining as part of the SAID. Since, at this point in time,
there isn't yet an online draft of the IPSP, I think it is premature
to say that important issues like this one have been settled.
