Interesting. I did find such a video on youtube, and the stretches appear to be similar to the ones I encountered in Butler's book.
The one video that I sampled, though, was entirely focused on the wrists. One interesting thing about the way muscular tension is networked throughout the body is that when one muscular group is compromised, another will compensate. This ultimately can cause a network of failures, so stretching all of the upper body, at the very least, is important in properly solving the RSI problem.
I'm sure an ancient art like Aikido addresses the whole body properly, but I thought it worth mentioning.
Aikido's all about moving "from your center", moving your body as a whole. It can sometimes go into mystic-sounding "chi"/"ki" talk, but precisely verbalizing things that often depend on really subtle timing and positioning is hard.
