As someone has mentioned earlier, flying above 250K while below 10000 contravenes ICAO. In the US you CANNOT fly a jet below 10000 greater than 250K UNLESS you are on a recognised IR or VR route. The point here is that the rule may come in someday [read - be enforced], but there are ways to manage the issue - I'm not suggesting that we go to the US low flying system, we will manage the rules by legislation.
Aside from that, there is some real cr^p being thrown around this thread - but then it has made me laugh at some of the ignorance!
