OK, looking forward to it.

I think so. What this should do in LilyPond is write the highest point 
of the top-most staff and the lowest point of the lowest staff to a 
file, e.g. <basename>.extent. The format is pretty much irrelevant, but 
the best would probably be to simply have two numbers, i.e. this as the 
single line in the file:

-3 4.23

referring to a file that spans -3 to 4.23 staff spaces around the middle 
staffline.
