 machine at a station which had a multiple in-out sound card (with 8 in's
 and 8 out's an M-Audio Delta 1010lt) and I'd set it up to be able to -
 from one computer at the station - have 4 different stereo incoming /
 outgoing connections at the same time, each one with different audio.
 OpenOB was on the back end making it all work. 
Got that now!
  Essentially I ran several different instances of
OpenOB at the studio
 each on different ports.  I'd establish both send/receive channels
 (again on different ports) to each location.  On the Studio end I'd
 routed it all through Jack.  Of course this means with some jack
 disconnect/connect commands it is easy to change where audio goes.  The
 studio end all ran on a single computer, just with multiple instances of
 OpenOB.
 The biggest trick to keeping it all working was to be very specific
 about documenting it all.  Without solid documentation it would become
 easy to incorrectly route audio to the wrong location.
 So as an example:
 Remote location 1 talks to Studio computer - OpenOB 1, on a particular
 set of ports
 Remote location 2 talks to Studio computer - OpenOB 2, on a particular
 set of ports
 Remote location 3 talks to Studio computer - OpenOB 3, on a particular
 set of ports
 etc 
OK
  Studio OpenOB 1, 2, and 3 all ran on the same
computer, just as
 different processes and using different Jack connections.
 Route it all in Jack at the studio.  If you want location 1, 2, and 3
 all going to the same audio output at the studio then Jack can do that
 for you - just route the audio from all 3 OpenOB's to the same audio
 card output.
 For extra security you might want to consider having the remote
 computers establish a VPN connection into your studio.  OpenOB by itself
 is not secure, I would not recommend using it on the public internet
 without some added security layer. 
Already do this
 
 Hope this helps. 
It does, many thanks for you help.
