Two lasers sharing a fake box is indeed bad - lasers go off during runs on
their own. It is nice to be able to flag that correctly.
LED sharing a laser box is ok, although the calibration software currently
depends on fake box to sort out laser and LED events - that's fixable.
Bari box sharing with LED box is the best idea so far. Potential problem - if
The Powers That Be ever do an about face, and let us do monopole calibrations
during normal runs, we have problems.
Putting in a lot of extra cards is obviously the most thorough solution.
However, the hardware is not immediately available, and once it all gets sraped
up, our supply of spare ERP parts will be dangerously low. That's 8 more S&H's
and 8 more TPU boards, folks - that's a lot of extra cards.

Alice is the grand high overlord (overlady sounds weird) of that part of bmon.

It is a given - any change to macro breaks dst production and produces mad data
managers.
