We really don't encourage people to do voice or video using any of the
in-band options. That might be appropriate for file transfer (you want
to make sure the file gets there, but time is not critical), however the
kind of performance you'll get from in-band bytestreams will not be
acceptable for voice and certainly not for video. Plus your jabber
server might fall over from the load. :)
