Wai,

Please explain how "the in and out channels are mixed first before they 
are written to the disk" using "monitor with no mixing onto the scsi 
drive."  I'd love to implement this on our system to cut in half the I/O 
associated with Monitor().

Also, what bug does MixMonitor() have?  It is my understanding that 
MixMonitor() is based on ChanSpy() and we seem to be having an issue 
with ChanSpy() where the legs of a call fall out of synch.  My hunch is 
that it has to do with a caller being muted or placed on hold.  Do these 
issues seem related?
