Rohloff Speedhub DIY? - Anyone have experience installing a Rohloff on mid-drive?

[Tom@WashDC]

Hi,
I've got a Luna Z1 Carbon Fiber mid drive. I am considering installing a Rohloff Speed hub in the rear instead of my Sram cassette. Does anyone here have any real world experience doing this?
I ride 50/50 paved trails and off road mtb style.

Thanks
