Yes, somewhat similar. Thanks for the link. The major difference here is that Pepe runs on a mix network similar to I2P, this helps hide your identity whereas anyone can see what you are doing with plain Bitcoin.

To answer the question in your comment: yes, you can install and configure I2P, you can install iMule on top of it to exchange files and some distributed forum to post on. But the usability of all that is really low even for a pro-user. The performance is also not great because those systems were not designed to be used with each other from scratch.

I wonder if it's possible to implement this via WebRTC and javascript? This would make it compatible with everyone with a browser, without need to develop an application for every platform.

One stumbling block would be addressability without TURN.
