If the algorithms, information, and programming manual were public on site
somewhere I could find, anyone could program their own program to emulate
Zillions. I would use it, even if it cost some money to use. Maybe if they
don't want all lose money, they could make a license to say 'You can't
distribute programs that use this algorithms because is patented', but I
disagree with the fact that you can patent computer programs anyway.
