From the NY Times article from 28 May 2008:

“It’s pretty clear that there was an enormous amount of discrimination against brokers who were trying to use innovative business models,” including discounted fees and virtual offices on the Internet, he said. “There are lots of entrepreneurs who have been looking for a green light in the form of this order to begin offering discounted rates. It has the potential to be a big step forward for consumers.”
