I'm interested in this, so feel free to mail me the patch if it's less
than 5 MB overall. Otherwise some mailer will delete it.

The 230 has a stereo input for an external audio device. In the web interface 
you can change between using the internally builtin mike and and an external
source. The internal mike is ok if you're within a few meters range to the camera 
and speaking in it's direction. At LinuxTag I used the 230 to record some talks 
and connected the speakers mike via a professional mixer to the camera. This worked
very good. However I haven't found a good microphone to use to tape talks in a 
discussion around a table. Most video conferencing systems seem to have such devices,
but they don't provide stereo outputs but digital signals I was not able to feed into
the camera.
