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"

I found cspace (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.
