Mind-boggling ideas! Sounds like good topics for a couple of
research projects in Artificial Intelligence.

How about the liability for people breaking their fingers while
trying to follow the fingerings?

I've seen programs that take a piece of text and determine some 
kind of readibility index. Some aspects are not too hard to find
out from the file - speed of fastest notes, use of large intervals,
uncomfortable keys (instrument dependent), number of simultaneous
notes (for piano music). The rhythmical complexity is a common 
source of problems in contemporary music, I wonder how you could 
measure that? In information theory, there are methods to determine 
the randomness of a sequence; that might be an approach.
