Rohloff hub (disc) on Santa Cruz Chameleon?

Anybody have any experience w/ a disc Rohloff hub on an older (2002 i think) chameleon?
The older chameleons have the disc brake attachement that goes under the frame.
What gears have worked such that one doesn't need a tensioner and so that the disk works?

Are there any mods that need to be done in order for the torque arm to fit?

I'm started to look into the Rohloff again as i've gone through several derailers and have bent my Der hanger back more times than i can count. Any help and pics would be greatly appreciated.
