Nick Mainsbridge has already done some work on DDP export support. I'll
let him weigh in with whatever he's done so far.

The first question that needs to be determined in this area is whether
we actually need to obtain a license to support DDP in the first place.
If its easily "reverse" engineered, the situation is entirely different
(there are no rules that protect file formats, unless they are
encrypted). I don't know how Nick has done whatever he has done so far.
