Excellent piece about how ham-handed approaches to traffic shaping impact real businesses, and that by denying the practice exists only causes further problems.

How Network Non-Neutrality Affects Real Businesses | Xconomy

My company, Glance Networks, has first hand experience. Glance provides a simple desktop screen sharing service that thousands of businesses use to show online presentations and web demos to people and businesses worldwide. When a Glance customer hosts a session, bursts of high speed data are sent each time the person’s screen content changes. The Glance service forwards these data streams to all guests in the session, so they can see what the host sees. The streams need to flow quickly, so everyone’s view stays in sync.

One day a few years ago, our support line got a spate of calls from customers complaining that our service had suddenly slowed to a crawl. We soon realized the problem was localized to Canada, where nearly everyone gets their Internet service through one of just two ISPs. Sure enough, posts on blogs indicated that both of these ISPs had secretly deployed “traffic shaping” methods to beat back the flow of BitTorrent traffic. But the criteria their methods used to identify the streams were particularly blunt instruments that not only slowed BitTorrent, but many other high-speed data streams sent by their customers’ computers.
