As stated in the article above (URL), it could happen, but I'm hoping that it will not happen. Repeal would surely hurt small banks. Recently, a huge S&L moved into town posting over market rates on CD's and other products, placing adds on TV, etc. The big players can easily bury small banks through loss leaders and adding the payment of interest on business deposits to their bag of tricks would not be good for the system, unless local market factors also require consideration.
In other words, deregulation doesn't work very well, e.g. telephones, airlines, etc.
