the intention is not to incest the container with the transport,
but to 
- store N streams in a single NUT multiplex
- identify which of the N streams belong together (in what mpegts
calls program: 1 video, 1+ audio etc) by means of some
info packet.

Requiring multiple NUT streams is simply not practical and 
out of question in certain environments (e.g. broadcast channels) .
Simply look at how difficult it can be receiving crappy rt*p streams
that require more than 1 socket.
On the other side having a program map shouldn't require much
of an effort
