I like this proposal.  It got lost in the email noise the first time around.  It's not exactly what Jamie proposes, but it could be made compatible with it.

+-----------------------------------------------+
|frag(1)| ???(1)|opcode(6)| Length(24)          |

It makes new protocol features transparent to the framing layer.  All you need to do is define a negotiation for the features.

It's a shame that it doesn't work for multiplexing.
