Your program receives the DTMF out of band. It would be easier if the DTMF 
event included the file "interrupt" offset and the S command allowed you 
to specify the starting offset... Bounty?

I'm wondering if you could do anything with specifying a named pipe to S 
and specifying the starting offset to the process filling the pipe?

A VERY trivial example is available at http://www.sedwards.com/mfe.c

How about another tack?

How about an AGI playing ("stream file") a series of short "music" 
segments while checking for your external event. (Remember that AGIs can 
be multi-threaded if your external event needs it.) Then use "control 
stream file" for your content playback?

Can you reply with a bit more narrative about your application?

What is the external event?
