Actually, it is not an European rewrite.  What PGP-i uses is the original encryption library from PGP's author Phil Zimmerman, which cannot be used in the States because of the RSA patent.  RSA wants to keep the algorithm under complete control, so they won't allow any implementation other than their own to be distributed, not even the free one from Zimmerman.  Because of that, Zimmerman's library, which is said to be better than RSA's (and compatible at the interface level) can only be enjoyed outside the United States.
