everyone, who know basics in programming can write such app in less than hour.
i did it for myself long time ago.
peace
I guess it depends on how much experience one has with creating programs that mine for data. Here's one of 5 files required for the program:

So, less than an hour to write five files just like the one above and actually have the program work? I'm sorry to say, but not everyone can do that! I think an experienced programmer might take more than an hour....I consider myself more of a theoretical computer scientist and don't have much programming experience per say. I'm not saying I couldn't do it but I know it would take much longer than an hour...LOL
