That's very nice for the paper pushers, but it will have little to no effect.
What's particularly amusing is the fact that a huge chunk of the gambling traffic is routed through a "bullet proof hosting" center on the Kahnawake Mohawk [en.wikipedia.org] reserve that sits on the Canadian side of the St Lawrence Seaway, with easy access to the US. The reserve is a bit of a legal no-man's land. The members of the band claim to be either Canadian, American, or neither, depending on convenience. They have a long tradition of smuggling in both directions, are renowned High Steel workers, have enlisted as Canadian soldiers in numerous wars, and a number enlisted with US forces for Vietnam and other wars.
They erected barricades, and effectively declared war on the Government of Quebec over the proposed expansion of a golf course [en.wikipedia.org]during the 90s.
The golf course was never built.
To this day, the Surete de Quebec, the RCMP, and the Department of National Defence want nothing to do with the place, the US government calls it "Canada's Problem", and it remains the only place in continental North America where internet gambling sites are openly hosted.
My point? The internet is everywhere, and nowhere, and as long as there is some place where the rule of law is weak, and international law disdained, there will always be internet gambling.
The US, Canadian, European Union, Japanese, and whatever other governments just waste their time, taxpayer's money, and deny themselves a source of revenue, by constantly holding talks on the subject and enacting silly, unenforceable laws.
