Having a U.S. based business serve as a sort of global corporate registry broker will also make it extremely easy for U.S. law enforcement to subpoena information that would otherwise be located in less cooperative jurisdictions (or in jurisdictions that are cooperative but just require a lot of paperwork and MLATs and so forth), so I can't imagine you'll have too much trouble with them.
