The Federal Communications Commission (FCC) recently revealed that it will begin investigating how it should regulate Internet-based telephone calls. The calls, which use a technology called Voice over IP (VoIP), are often cheap or even free today, and many industrious users are starting to use their PCs to place inexpensive (or free) long-distance and international calls to other tech-savvy users. But fear not, folks. The FCC says it isn't interested in screwing up the latest cool technology to come out of the Internet. "IP networks cost much less to build and operate," says FCC Chairman Michael Powell. "We will not dumb down the genius of the Web to match the limited vision of a regulator." My goodness, that's almost common sense.
