Pirates!

Maybe it's just me, but I see a huge opportunity here. First, let's look at what's going on. Pirates, who don't have to follow any rules, can carry weapons and take over just about any ship they choose because those ships have to follow rules that don't allow them to carry arms (mostly because the ports they go to don't allow it, not because of any rule in the open waters). So, seems to me a well-armed ship could be hired out to escort the unarmed ships from port to port. The escort ships would never dock so they wouldn't be breaking the rules of the ports. They could have their own support ships to bring them fuel, food, etc. And, they'd probably be a lot cheaper than paying ransom to the pirates.

As an aside, anyone really think there is any chance of there being another Pirates of the Caribbean movie?
