I could swear I saw one of these at my local dealer (International MINI, Milwaukee). The outside top is cloth, and the motorized roof slides back across the entire footprint of the "normal" moonroof. The fabric bunches up towards the back, so I suppose the total opening is probably only slightly larger than the normal front pane opening on a glass moonroof. I didn't look closely at the window sticker to find out the option cost/details.
