Sure, it's not quite that simple though.  The unix domain interface
would be very very low-level.  The messages would pretty much get passed
directly to the domain's ring queue.

The ip interface might support SNMP or some other standardized network
protocol.  In the very least, the IP interface would have to be
endian-neutral which means that it's going to be a more complicated
protocol.

Feedback is always a good thing.  I'm very curious to see what people
would want the control software to do.
