+- thinking about the whole external connectors question.  After meeting 
+  with Art, the idea of using 3 and 4 pin XLR connectors which are cheap
+  and available in right-angle PCB versions is appealing.  To allow 
+  mounting in an ammo box, where the main board stack would like to be
+  mounted to the top but the connectors should project through the hinge
+  end face of the box, it would be nice to have a distinct PCB with the
+  external connectors that could be mounted and use a ribbon cable or
+  something to get back to the main PCB to avoid lots of manual wiring
+  harness stuff.
+
+  For lots of flexibility, I could imagine a single circuit board with
+  one end having PCB mount external connectors, designed with split
+  planes and a couple micromatch connector footprints with traces 
+  putting them in parallel across the "gap".  So, you could cut the 
+  two boards apart and use a ribbon cable with connectors to hook them
+  together, *or* you leave off those two connectors to mount it as a
+  single circuit board?
