this is fine. however, we should also start putting together a draft of 
possible milestones.

good idea.

Fernando Barbosa could also address some front-end electronic issues

Ed Jastrzembski (or Fernando) would be the right choice

Ed and David Abbott have been thinking about data formatting issues 
related to the TDC

Missing from the list is a discussion of
infrastructure/grounding/cabling/etc.  Chris Cuevas has background in many
of these issues and perhaps could provide a draft/guidance here.
