-- use software volume when hardware doesn't support all channels (alsa done)
-- silence generation should be moved into the core to avoid races and code
- duplication in the backends
-- pdispatch: split large memory blocks when sending
-- don't read/write audio data from/to ALSA devices if noone is listening
+- module-tunnel: more reliable audio streaming over wifi
+- Compressed network streams for tunnels/rtp streams. (Might be a good GSoC project)
+ This builds on passthrough support. A good candidate codec would be CELT.
