IBM has been granted a patent on a system which would monitor vehical traffic on the "premium" lanes of a toll road (presumeably using EZPass-type technology) and automatically adjust prices for those lanes to ensure they don't become congested.
Quite an innovation.
I'm going to sit down and write a script which uses information on housing prices and zip codes to advise merchants on how much to charge customers in those zip code areas. Then I can get a patent on price discrimination, too.
