Sorry, no detailed notes (too busy right now) but this seems to work. If you read my notes for other versions of ASA you should be able to figure out what is going on.

crypto map outside_map 1 interface outside

One thing I did learn is that if you already have a crypto map defined and associated with the interface you want to use, you should add the new rules with a different number to the existing map, rather than trying to use two maps at the same time. That's outside_map here, so if you have a SYSTEM_DEFAULT_CRYPTO_MAP defined, you should add the rules to that existing map rather than defining the new one.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
