The Economist takes a look at the incumbent telco’s ill advised expensive IPTV plans (turning 2 way broadband internet into a one way TV dump) and the possible, subtle methods used to derail competitors:

Stoyan Kenderov, an IPTV expert at Amdocs, a firm that makes back-office software for telecoms companies, says that the telecoms firms are building into their residential gateways new technology that will inspect the packets of zeros and ones passing through. This will let them identify traffic from third-party rivals, which might then end up at the back of the queue and thus be slow and patchy. The only hint that users might have of that going on, says Mr Kenderov, would be some very fine print on their bills explaining, in turgid legalese, that the provider guarantees the quality of its own services only.
The telecoms firms counter such suggestions with well-rehearsed indignation. In a hearing before the judiciary committee of America’s Senate in March, Edward Whitacre, SBC’s chairman, said in emphatic Texan that “SBC would not block any Vonage traffic or anybody else’s and has never done that, would not do that. That’s not the way we do business, and it’s just not going to happen.”
