Okay. Can I assume that this can wait until I have the hardware side
of the project well under way?

Actually you wouldn't have had to reboot the system for this. The
real-time CPU will be running linux, so one could simply have a script
which invoked ssh or rsh to remotely kill off one server process on
the target system, then run the other.

Currently the message IDs are taken from an automatically generated
unbroken sequence of numbers starting at zero. These are then offset
by the value of the CCB_BASE_LOGID macro in ccblogid.h, before being
presented to the manager. Thus by changing the value of the
CCB_BASE_LOGID macro, I can easily shift all of the ids to higher or
lower values to avoid clashes with other Green Bank software. If this
is what you mean by "re-sequence", simply send me the new offset and
I'll install it.

If you simply want me to include a flag in the returned data to
indicate whether the data pertain to a primary scan or an intra-scan,
then I can easily do this. Is this what you are referring to?
