I'd recommend opening up a multiplexing discussion using this as a 
draft/working model, and putting off the extension discussion for now, 
because the needs of a multiplexing extension would affect the basic frame.

(And also because discussing extensions can become impossible because 
everyone has a different vague idea of what kind of extensions might be 
possible/desirable, while multiplexing is concrete.)
