Some tasks on the list:

NEST into LArSoft
Categorizing where the time, memory, and space in the output files go
Andrzej's claim at the tracking meeting that the e+ and e- from photon conversions
  are so close to each other that their Birks' corrections should not be considered
  independent of each other.  My guess is that they separate quickly due to scattering,
   and that it only takes a few atomic widths apart for them to have separate Birks'
   corrections.  In any case, this would have to be checked with data
Wiki page with LAr properties
Photon collectors
LBNE geometry (that's an LBNE issue, not a LArSoft issue, but I have an interest in it)

FLUKA interface, which may just end up being
Text-File interface to arbitrary generators.
