        for guaranteed privacy, luckily there are already a few standards like ZRTP/SRTP and OTR.


        ZRTP/SRTP is a standard about how to establish an encrypted media channel (audio or video) over any standard RTP media channel. So you can already use it with any RTP-based audio/video protocol.
        For exemple, Jingle/XMPP uses RTP for audio/video calls, so two users of google talk can call each other securely, as long as both ends use software with support for ZRTP (and as long as Google still keeps the XMPP gateway running while consolidating their services as Hangout).
        As another example, the SIP standard for VoIP used by virtually "any other VoIP provider except Skype and Viber" also uses RTP for its media channels. So it's possible for to users of the same sip service (or even users of 2 different services allowing call between them, like iptel and ekiga) to call securly, as long as both use a ZRTP supporting software.

        Jitzi and Twinkle are 2 exemple of software supporting such encryption.
        (Note: Ekiga doesn't have it yet, but it's planned for a future version)


        OTR is a standard about encrypting text-messages over any channel transmitting regular text-messages. As long as a protocol has a system to transmit text messages, and both ends have OTR, messages can be securely sent and received. (That even means it's possible to sent encrypted message over the Skype netword, as long as encryption happens in a layer above, before sending the encrypted form to Skype through Skype API to send on the network). (Of course, if you use OTR on Google Talk, Facebook and Skype, the history on these platforms looks like garbage, only the OTR supporting local software gets the clear message)

        Jitzi, Pidgin, Adium, and lots of other do support OTR, either out of the box, or through plugins.


        in short: opensource end-to-end encryption of both text and audio/video is possible as of *TODAY* while running over protocol for which you probably have an account (Google, Facebook, etc.)

        you might be interested to look into sipwitch.
        it works using the already industry standard SIP.
        But instead of connecting to some central server on the internet, you connect to a daemon running locally and handling the VoIP network in a distributed manner.


        In short:
        - it is possible to have decent opensource end-to-end encryption over several existing popular services AS OF TODAY.
        - distributed networks are being in the design/building stage.
        - what we need is visibility, user friendliness and marketing (Jitsi is a nice step in right direction).

          Hmm

          So today i was talking with somebody and they brought up Viber out of the blue. Said they were using it to communicate with family in the phillipines, and it was working great.

          That was the windows version, but i just wanted to put it out there. I'd never heard of Viber before, but it sounds like they're on the edge of becoming mainstream.
