To Do:
- Near Term (May):
  - Hall-B FT calorimeter and hodoscope streaming readout test - Pending OK from Sergey B.
    - May be able to use Abbott's indra-s1 setup
    - May be able to use new VTP f/w with Hall-B VTP's - (Ben Raydo)
    - CODA 3.10 + ERSAP for new VTP f/w
    - CODA 2.0 (non-streaming) for old VTP f/w
    - Diagram

    - parallelize writing of raw data files
    - distribute raw data across multiple compute nodes for calibration skims
    - 1 Gbs at hi-luminosity
    - Control Plane
      - Will interact with SLURM
      - Python based (?)
      - Control Plane daemon for compute host (?)
      - Demonstrate CP based flexibility/elasticity
    - Hall-D comms with DAQ 109 subnet require network customization; DAQ 29 subnet available
