There is a bandwidth problem. High-quality audio is compressed on the
fly before transmission. We will probably be able to build in the delay
to the video player so it slips the video stream a bit. gstreamer may
even have a way to specify in the codec plugin how much latency it
introduces.

Some of these problems could be fixed if a new audio spec was written
that required the extended data rate of bluetooth 2.0 and left out
compression.

The a2dp spec says nothing about duplex high-quality audio, but there's
no reason a headset couldn't try to connect back to the source node on
an independent connection when it starts receiving audio. That's
basically how the AVRCP connection works.
