It's unclear to me how this project does anything to protect the identity of users or who is talking to whom. It's nice to know my messages can't be read, but if my ISP can see who I'm talking to and how often it's not doing much.
Also how to clients find one another? Tor and i2p sites are notoriously require friends or public wikis to share the addresses.
Agreed, if you need anonymity, use a VPN or other tunneling software to obfuscate your identity, or provide multiple identities. You can run it open on local networks that you trust, say for a life planner DWA that syncs between devices on your home network, otherwise protect your line as you normally would. With a VPN/tunnel you can attain privacy plus anonymity.
Clients don't find one another, they're instructed to connect with each other (very briefly) by users, then everything is passed off to your browser. You will need a friend's address (either IP or domain) to connect.
