Perhaps my problem is that I am not exactly sure what the goals are.
Cleanup (BL mixed in the BL seems wrong)? HA or performance (are people
hitting limits that are traced to SQL) ? Flexibility/Research
(plug-able modules for experimentation)? I think it would help scope
the effort (and temper my concern about the work/reward ratio) if they
were enumerated in clear place.
