Neutrality ain’t exactly what you may think it is, you see:
The U.S. House of Representatives recently passed legislation allowing Internet Service Providers to do traffic shaping, giving some priority to certain types of content, which would presumably be either the ISPs’ own content or that of ISP customers paying a premium for such access. The U.S. Senate is considering similar legislation, as well as other legislation designed to do exactly the opposite — guarantee that all data packets receive equal service. The prevailing assumption, by the way, is that right now all packets ARE created equal, which of course they are not.
Some pretty good detail on how the Internet actually works follows, but he gets all conspiracy-freakish at the end.
IPTV and VoIP are two examples of applications that need priority service, and there’s also that whole issue of payment. Read a lot, you’ll get a little here and a little there that sheds light on the issue, and you’ll pay for your illumination with propaganda.
