     John Gilmore dug up the Cspace software (see below), and I believe
     this is
     the Trilight software/service mentioned in the NSA docs:

     Nice to hear that there's some software that makes NSA go deaf, dumb
     and blind.  Here is the Snowden release that mentions it (page 20):
        "Presentation from the SIGDEV Conference 2012 explaining which
     encryption protocols and techniques can be attacked and which not"
        [13]http://www.spiegel.de/media/media-35535.pdf
     I found cspace ([14]http://cspace.aabdalla.com/), which was a bit
     obscure
     and hasn't seen any maintenance since 2009 or so.  Its dependency
     ncrypt-0.6.4's source code is at Pypi and ncrypt-0.6.4 is in current
     Ubuntu distros.
     But I haven't yet found Trilight Zone.  Any clues?
     And I haven't found a reliable, usable, simple, free software VoIP
     client for Linux, let alone one that uses ZRTP.  Though I admit I
     gave
     up on looking about a year ago when I couldn't get anything to
     actually work.
