Seriously, what is wrong with everyone and these questions. They closed down all these things a long time ago. You 1) go and live in that other country; 2) you have a base in x and move backwards and forwards on 'working-holidays'; 3) you pay it and enjoy life wherever you call home.
Anything else is just plain stupid, the tax system is so complex that the accountants have no idea themselves, have experience of that screw up. So when they mess it up, you will be left with a bill you can't pay, the accountant saying "but it's your responsibility" which they always get away with, and then run as fast as they can as you can't pay their fees any longer. Basically doing that you are a duck unwittingly flying through a duck-shoot, that's your odds!
