No, but twinkle is GPL and use ZRTP: http://www.twinklephone.com/
And it should work with Zfone.

Yes, but this gives us a better chance to do it right: end-to-end encrytion.

we use twinkle on the Polippix live-CD.

Of course you will not be really anonymous because the recipient will 
recognize your voice (you can try to disguise it).

Using Twinkle with zrtp on a laptop with macchanger on a public wifi 
network seems to be the best alternative to TOR. Maybe TOR voip will be 
possible when TOR get UDP support.

Calling POTS is anonymously is difficult because of payment. But as 
prices go down it makes it possible that we all share one account 
financed by donations.
