+safety
+ rtprio
+ passes on all pic traffic
+ safety incl polarity, no collisions, curvature, etc.
+ converts instructions to/from text
+ takes instructions only from multiplex
+all real-time stuff so clients can be confident of no misthings ?
+ on-event for point changing, stopping, etc. ?
+ specify intended path and speed profile for each train ?
+  - list of points, in order, with setting
+      this is good enough to be in time for shinkansen on inner loop
+      inner loop is			 3589mm
