Thanks, Jatinder; I saw the minutes.

Just so folks know - it looks like in the HTTP world, the protocol used is going to be keyed off the registry defined in ALPN:
  http://tools.ietf.org/html/draft-ietf-tls-applayerprotoneg-01#section-6

... so it might make sense to just refer to the registry.

In HTTPbis, we're also going to be using temporary identifiers for draft versions:
 http://http2.github.io/http2-spec/index.html#versioning

Cheers,
