Thanks Pantxo.

I'll try to bottom post any future communication.

And will investigate add_input_event_hook.

So i guess the idea would be to write first write function which
checks a well-known location in the file system, reads and deletes
what's there, and responds accordingly.  Then i would schedule that
function with add_input_event_hook.  Maybe could even put the code to
do all this in my init file, and have a lock in it somewhere so that
only the first octave i run will actually do the checking.

Yes, that is basically what I would do. For a more sophisticated (and network based) server/client logic I would look at "socket" or "zeromq" packages in octave-forge:
