After Symantec acquired PGP, Inc. in June 2010, Phil lost the hosting for his project, which had been provided by PGP, Inc. PGP, Inc. had their site setup so as to comply with U.S. export regulations; remember Phil had been put through the wringer for 3 years by U.S. Customs, who suspected him of violating U.S. export laws. Needless to say, he didn't want to go through that again. Phil apparently didn't have the money to setup another secure server, so essentially the project is abandoned. (One can still find the software on the Net if you know where to look.) Phil has now started his own subscription service, known as Silent Circle. The ZRTP protocol, which served as the heart of Zfone, is also available in a software package known as Jitsi (formerly known as SIP Communicator). This is the software recommended by Jacob Appelbaum, one of the Tor developers. One thing you must bear in mind is that Zfone/Jitsi is for _privacy_ -- it provides NO anonymity. Using either software, both of the endpoints are known and/or discoverable. The IM/voice traffic will be encrypted, but it will be obvious to the authorities that you and another party are communicating. As such, traffic analysis can still be used to build up a map (or network) of one's associates. Finally, both parties communicating must have a copy of this software installed for it to work; this is highly unlikely to be the case if you're dealing with run of the mill buyers, most of whom would be as security-conscious as a stone.
