(BTW, email formatting makes it very hard for us with challenged MTAs to distinguish between the different parties in these emails).

Ian,

I think that perhaps you misunderstood the proposal.  The idea would be to embed the metadata in the frame.  My initial suggestion was to go full MIME and have a MIME payload, including headers in the frame body.  Header and content are separated, as they are in MIME by two end lines (\r\n\r\n).  Greg is suggesting that we could define a more efficient container for these.

I don’t think that the idea of having separate frames was ever a starter.

If I had to choose between Roberto's and Martin's, I would prefer Roberto's simply because I worry that if you have metadata that changes between messages, e.g. you are multiplexing a number of streams, you will end up sending a control frame before each data frame, which sort of defeats the purpose, makes it extra chatty, and opens us up to issues of frame injection as well. So, I prefer to have whatever extension/meta-data associated with the frame itself.
