- valerio: drp communicate with multiple python processes
- mona:
  o routines to modify dgrams from python
    - look at dgramCreate.pyx
      https://github.com/slac-lcls/lcls2/blob/master/psana/psana/peakFinder/dgramCreate.pyx
      also the test test_py2xtc.py
      goal: receive the raw-dgram, and return a fex-dgram with the raw (how do we do this return?)
      data removed (almost always) and put in fex data.
  o think about calib-fetch scaling (lower-priority)
    - ideally independent of mpi. zmq approach? how do we
      determine "supervisor"?

Json2XTC Option

drpDG -> psana calls createsjson -> drp calls Json2Xtc

- need to make sure json2xtc can separate the Names (configure-only)
  from Shapes/Data (l1accept)
- cpo worries about performance of the extra json step
- cpo votes to try dgramcreate approach(with 75% confidence level)
