NPPS Leadership Team

[Alexander Kiselev <kisselev AT mail.desy.de>]

  Hi Chris,

  I think we should have a fair conversation with the JLAB guys tomorrow.

  My main concern with this community reconstruction work is that the 
initiative comes at the very wrong moment in time. I guess, given the
pre-history of these efforts, we need a schedule with deliverables, and
if the activity again starts lagging behind badly, behave accordingly.

  Developing the library (or call it plugins) with some neutral interfaces 
can at the end be the only part we seriously commit for, at the beginning.

  Since sPHENIX has no RICH, I understand your answer to my question
about "EIC postdoc" non-sPHENIX activities is YES, right? :-)

  Cheers,
    Alexander.
