I might end up going in that direction.

I guess I was looking at the mount point as a shared pipe that I could 
stream to and a client could acquire the stream from with icecast 
managing everything.

So from the Icecast perspective the mount point is a place the listening 
client connects to only?

So I can redirect to icecast like:

cat ./my.wav|oggenc - |/usr/bin/icecast

but I'm at the mercy of the file system to determine the rate that 
icecast gets the data stream - correct?

One other tool I was looking at was ffmpeg.  Not only can it re-encode 
the stream on the fly, but it can send it at the correct data rate for 
the encoded stream.  Only problem is there isn't much written concerning 
re-encoding .wav files.

Is there any documentation anywhere that I could read to learn how to 
write my own source client?  Something like that might explain a lot.


Thanks for your help.
