  Using JEP-95 and agreeing on some common 'we suggest' mime type, such as
rtp, does this.

  Once again, codec has nothing to do with jabber.  We can suggest
options, and in the end, chances are, no client developers are going to
write thier OWN software to do things like RTP.  They will use some
external library to handle this, which will inevitably support existing
standardized codecs such as G.711.

  So the solution is simple.  Just nail down the developers options by
locking down the protocol..  (Yes, I have my tounge FIRMLY planted in my
cheeck)

  Again, I fail too see how a jabber server would be required to support
ANY of this.  WHAT part of the servr would have some required change to
support the negotiation of a stream, beyond the obviouse of perhaps
wanting to offer the ability to offer as a gobetween for a raw socket in
the case of boxes behind NATs?  IF this IS the case, then pull back the
wayback machine and visit JEP-03.
