Re: PayPal and others may be able to "keep up with the regulations"...
Wow - this used to be a technical website.
E.g. IP addresses could be generated dynamically on the fly if there was a routing problem, and sent to the region (e.g. the US) where the service is located. At the point of entry the IP address would be translated to the real IP address.
So, the sending country only knows that packets are destined for the US, with an otherwise fairly random IP address.
I thought of that just off the top of my head. I'm sure people could come up with other stuff.
