I am not a tax lawyer but the issue of foreign taxation is more complicated than 'organize in the caymans and save lots on taxes'. You're still going to have to pay taxes for any business that you do domestically. If you have income domestically you pay income taxes domestically. If you have domestic sales you pay domestic sales taxes. If you have international sales there are all sorts of complicated rules about where those sales must be recognized. Most of the large corps that use this technique are doing it to shield foreign income from US taxation. They can park it offshore and reinvest it internationally without US taxes. Once you bring it back to the states you have to pay income taxes on it (I think you get a credit for foreign tax paid). So if you need your foreign revenue to pay the domestic bills you're going to get hit. Also I believe that a couple of years ago Congress made it more difficult to do this sort of thing after it started impacting tax receipts.
