I'd be interested to know what the % of international customers oposed to domestic are.
Of course it varies site to site but is something like this really going to hurt?
And a simple disclaimer stating what the site contains and if it violates your local law then you shouldn't enter (i mean that is already in most disclaimers)
Either way its pretty interesting. Imagine, either don't allow certain countries, or certain states access to site OR have a dynamic site that delivers legal content to various customers... WOOOO theres the future
