Test:
- module-combine
- module-tunnel

Fixes:
- better validity checking in protocol-esound
- change pa_log to not require \n
- proper use of memcpy in procotol-esound.c so we don't get alignment problems
- latency api for native protocol
- add support for auth using SCM_CREDENTIALS
- use scatter/gather io for sockets
- notification on hw volume change
- source volume control
- mute switch support (like ALSA does it)
- module-oss-* love:
  - deal with underflows propely
  - improve latency measurement for mmap
- module-alsa-* love: 
  - volume control
  - add hw driver name to sink/source description
  - deal with underflows properly
- multiline configuration statements

Post 0.8:
- alsa mmap driver
- add radio module
- dbus/hal
- polish for starting polypaudio as root/system-wide instance
- chroot()
- add threading API
- module-tunnel: improve latency calculation
- port from howl to avahi

Long term:
- pass meta info for hearing impaired
- X11: support for the X11 synchronization extension

Backends for:
- portaudio  (semi-done)
- sdl
- OSS (esddsp style)
