Along the lines of documentation... are we salvaging the last draft
intro doc or scrapping it? If we're scrapping it, what about it didn't
we like, what about it was good? The work on shoring up definitions is
directly applicable to the intro doc, but the minute details of asset
addressability and cacheability are leading us down a rat hole -- it's
interesting conversation, but just not productive right now.

Toward Carlo's mission of 'flexibility first': how would a statement
about the flexibility of the protocol appear in such a document?
