I'm down for Quechua, though if I go to Rome this fall I may not be around much. Actually, I'm probably down for most things, though my vote is cast for either Quechua or Cree.

One benefit to doing Cree is that there's an excellent three-part book course with audio that's just recently been completed- though we'd have some scanning to do. To my knowledge nothing of the sort exists for Quechua.
