What's the easiest way to flatten nested Options

The easiest and most generic way requires third-party library support
(see Scalaz). What you are describing is called a "Traversable" (see
scalaz.Traverse, specifically the Tuple2[T, _] instance).
This paper describes it best
http://www.comlab.ox.ac.uk/jeremy.gibbons/publications/iterator.pdf

It's a good exercise to play with these abstractions, so I'll leave it here.
