Ireland? CRO[1] gives details about registering a company and the requirements, and the New Companies Bill of 2014[2] will make things easier for smaller companies.
I was told by a guy who used to contract in Ireland, that there's a heavy crack-down on contractors working through their own Ltd's happening in Ireland, since they want you to pay taxes as a normal employee. Something worth considering, since it could also apply to foreign-generated income.
This might indeed be a problem for Irish nationals, just as the "IR35" rules affect UK contractors working through limited companies, but I can't imagine that a non-national working outside Ireland through an Irish company would suddenly be considered resident in Ireland for tax purposes.
