I would agree, and that raises the issue of the "wrapper" for HTTP streaming. Note that Apple uses MPEG-2 TS for the wrapper for its live http video streaming.

(  Each media file MUST
   be formatted as an MPEG-2 Transport Stream, an MPEG-2 Program Stream,
   or an MPEG-2 audio elementary stream  - http://tools.ietf.org/html/draft-pantos-http-live-streaming-01 )

While this is certainly standards based, I do not think it matches or interoperates with anyone else's HTTP streaming. And, of course, this is an I-D still. Flash also does http streaming, but I believe it uses its own, proprietary, wrapper. 

So, is specifying a media transport protocol for http streaming in scope ?
