frobozz, Ektagraphic claims to have had success with cinelab. I emailed them and never heard a thing, so IDK. Maybe it's not their idea of a good time, even though they'll do it occasionally. I think a lab could make a small side-biz doing this though
Try calling them. They answered and talked at length when I called. I think you'll have more success on the phone. I spoke with Brad. I'm personally too busy with Kodachrome at the moment to do anymore with this.
