There'll be way around it. If they don't know you've got the OS on your computer then how can they charge you?
Take their validation thingy for instance. An easy way to bypass that is to have Windows Automatic Updates permantly off, and don't connect online until you're sure they are. Works for us. Should work for everybody else. And it works because they send a nice little ActiveX component down the line to you that checks the validity of your product.
Or you can download a nice little Java Script that fools it. Either way there's a way around it.
Who knows. They're probably gonna let everyone get around it and sue the hell out of them for 100,000 dollars apiece until MS buys a nice sized country, say Germany, and round THREE BEGINS!
