Not really. You're going to want to sell your products in the US anyhow; the New Zealand market is tiny compared to the US market. If you sell your products in the US market, you have to play by the US's patent rules or your products won't be able to be imported (but as Samsung has found out, popular US based companies like Apple can get federal government intervention to veto an import ban on their products, but Samsung can't do the same: http://www.bloomberg.com/news/2013-10-08/samsung-loses-bid-f...).
What if the real money is in B2B and this is simply going to push the expenditure into a special trade communication zone? Are American companies going to be banned from certain expenditures? Is is it possible that people would create a proxy corporation to leverage the service in different areas?
I'm probably acting like an idiot. But I mean I think this just is creating a recipe for crazy lawyers to try some shit on someones dime.
