How do you know that the NSA isn't listening to those? It would seem more appropriate to make public-key encryption easier to use. There are already well-defined ways to use it with email, and there's OTR for IM that could be applied to multiple protocols. Granted, only the contents of the communications are hidden in these cases, but that's a big step forwards.

I'm sure the NSA is listening to Freenet, but it doesn't matter. That's the advantage of Freenet.

Among the disadvantages of Freenet are that it's incredibly slow, difficult to find content on, and cannot access content on the regular internet.

Everyone is listening to TOR, always ensure that encryption is in use. Always ensure encryption is in use anyways with anything important.

Furthermore, always ensure authentication is in use with anything encrypted.

I know of Freenet and Tor, but haven't heard of Phantom. Because the word 'phantom' returns a huge number of irrelevant Google results, I haven't been able to find the project. Care to throw us a pointer?
