My ideal solution for this would be to introduce an AAC format that
PulseAudio can directly provide, and clients can then deal with
decoding.

The challenge here is that you would need to deal with variable
bytes<->time conversion, which will potentially throw off latency
calculations. This should be solvable, though.
