Hmmmmmm....
I wonder if this has anything to do with the fact that ISO/MPEG
decided that there was no need to develop a new transport stream
structure for MPEG-4, and thus there IS NO MPEG-4 Transport Stream
standard for broadcast applications. All of that effort went into
mapping MPEG-4 into MPEG-2 transport.
That being said, there will be MANY wrappers for MPEG-4 content. The
requirements for wireless telecommunications are different than for
broadcasting, and different from web streaming.
John would be well advised to check out the ISMA and their positions
regarding MPEG-4 and transport.

P.S. and when Microsoft finally supports H.264, they will most likely
wrap the streams in their own proprietary transport format ( ASF).
