That sets off some alarm bells; isn't Perzo exactly the sort of unified communications platform that Google, Yahoo, Apple and Microsoft are trying to build for themselves? On the other hand, Gurle might point out, we now know that services built by any of these vendors can never be as free of surveillance as Perzo, built from day one to counter snooping.
There's little doubt that today's communications systems are getting more complex and less secure, partly because many of them were designed years or even decades ago but also because people now use them more intensively. Perzo could be a step in the direction of reinventing them for the early 21st century or another interesting cul de sac; time will tell.
