Here is a pano shot with Olympus E-520 with Zuiko 8mm fisheye used with R1 and EZ leveler on top of a Frankenstein tripod.

It was tilted 10° down, and one shot 90°up where I raise the center column to make up for the tilting, having drilled a hole in the column and putting a pin through the holes... brings the camera to the correct height in a few seconds... and moving the tripod the few cm's that are needed is normally ok... but can be made better I'm sure.
All in all: R1 is a perfect tool for both outside and inside jobs, especially when the camera height can be regulated as quickly as I do it with the zenith shot.
The only thing that might become an "issue" with R1, is the nadir shot, but until now I have not had any situation I haven't been able to photoshop over, or cover the hole with a nadir cap with a couple of clicks in Flashificator.
