Yes.  The firmware image is currently loaded from a binary data file which is 
distributed as part of our current drivers.

I'll work out what info/code we would need to release, and see if this is 
something management would agree to.

Models range from $995 to $3495

Historically our cards have very large buffers that contain seconds of audio, so 
that they can keep playing flawlessly even if the CPU or network gets bogged 
down.  Whether this is used or not is up to the application though.

Low latency has not been a design goal.  I would say the latency is between 
about 3000 to 5000 samples depending on processing details.
