But the judge would have let him establish merely "a personal privacy interest in the Icelandic server or any of the other items imaged and/or searched and/or seized", which sounds like "using", but not necessarily "owning".
Which makes it even stranger, because I don't know how the judge would reconcile that theory with the third-party doctrine, which (in my layman's understanding) seems to be about what you said; namely that since some person(s) shared all the information in the image with the ISP, it wouldn't be subject to anyone's Fourth Amendment protection. Or is there some line between a hosted email account and a VPS; where the email has been "shared" with the host, but the VPS's contents can't sufficiently be shown to have been "shared" and thus are still protected?
