Not to beat a dead horse, but this would be a perfect application for moving 
the arrays to memory databases, and running queries against them, then 
converting back to arrays again. I can have a go at it if I have a couple JSON 
arrays to work with. Are  they typical 2 dimensional arrays like datagrids use, 
or are there embedded arrays?
