It's not a problem if people see the two parts as distinct. After all, if
we come up with something which later can be reused to transport other
protocols (eg: WebSocket) without the need for HTTP semantics, it will
be a good thing.

I'm wondering whether we don't already have such things : 
  - HTTP holds the semantics
  - SPDY is the framing layer.

And if would 1) emphasize the fact that we don't want to change semantics,
and 2) acknowledge the work done by the SPDY team.
