1- a prog that records all items and their prices in ms 2- a program that searches prices in us without u actually haveing the item (like an autopricer... but u input a list your interested in finding the price)
I actually think both would be a bit unrealistic considering the sheer amount of items available on neopets. The first might be doable if you were just looking a perhaps a single shop but overall, I can't see the efficiency in doing this.
