Multiple Paper Submissions

1. Quick pass read by members of PC to eliminate papers that are in the
   wrong conference or don't pass muster.

2. Guarantee that at least one author will attend conference -- before
   shepherding -- but how can we back this up?

3. One author - one paper -- is this too harsh?

4. Only the author can represent the paper at a workshop, if author can't
   attend, paper is dropped from workshop
