I think we're on the same page. Each founder already has to answer "Will you live in the Bay Area January through March 2015, if we fund you?" and "Will you commit to working exclusively on this project for the next year?" in a drop down in the new founder bio page.
if numWontLiveInBayArea >= total / 2 then flag
and if numNonExclusive > 0 then flag
Could be totally automated.
