 	NAS *could* help here.  NAS aware clients will share the audio 
stream - ie: they will be mixed.  When NAS is not currently servicing any 
clients, it will, by default, close the audio device to allow other 
software to use it.

 	The key here is that all of the clients would need to be using NAS 
as their audio output device.  non-NAS aware apps can make use of Erik's 
LD_PRELOAD libaudiooss library (with certain restrictions) to fool OSS 
apps into talking NAS by intercepting opens/write/etc to /dev/dsp et. al.

 	mmap'd dsp driver's will not work with libaudiooss IIRC.
