In my opinion the native elements wouldn't do any encoding/decoding 
work: this is clearly GStreamer Job as a media converting framework.
I think we would have to:
   - extend the already included RTP GStreamer element to accept sbc and 
mp3 encoded streams.
   - wrap libsbc into a GStreamer element to do convert to do PCM to sbc.
   - create an a2dp Gstreamer element

..and that's all...
Then any enabled GStreamer application would be able to natively stream 
mp3, or stream whatever other format using sbc. :-)

Cheers,

Fabien
