Sorry for very late answer. Just one issue I wanted to clear regarding
that name of the MIME transport type (we've had this discussion quite
some number of times now...):

Wasn't it so, that the fine folks at IETF recommended two approaches over
time:

1: audio/vorbis doubly defined for BOTH stream (TCP), i.e in ogg-wrapper
   and RTP transport without wrapper

2. audio/vorbis for the stream, ogg-wrapper, vorbis audio data only over
   for example TCP and
   audio/rtpvorbis for the vorbis-over-RTP stuff

Which approach was chosen eventually? Right now it looks like audio/vorbis
is for RTP and RTP only, this is not good in my opinion, cause even if the
RFC obviously says: "use this MIME type for RTP transport only", it will
take about 2 seconds before the eager web site administrator find "Oh! A
MIME type for Ogg Vorbis! Then I'll serve all my HTTP Ogg files using that
instead of that application/ogg type they came up with a while back!"

These people don't read RFCs sadly, they just go by intuition. And
assigning a MIME type named audio/vorbis will intuitively be used for
everything, including TCP streams, and this is not good. audio/rtpvorbis
stands a much lesser chance of being abused.

Just my way of seing it...
