It is more a matter of corp structures in conjunction with countries - ie you may not necessarily operate in a country where your corps are founded.
If you mean as an operational base, there are a number of Caribbean Islands and several Latin American countries that are pretty helpful.
It really boils down to the fact that several countries don't actually have such things as "porn laws" - there is no need for them. Some have "part laws", but they are not related to anything like webmasting activity, - mainly common sense sex law stuff.
