These should probably be set as setable from the meta data. It is a
reasonable default, but hard coding it with out a way to change it is
probably not what we want.

Completely minor gnit. The copy here isn't needed until you start
setting the DL_DIR. Why not wait til after the check to see if we need
to do it.

Otherwise seem like a solid idea.
