Thanks for the comment. Yes, it also does something very similar. But, Magic Wormhole requires "Mailbox Server", to deliver messages from one to another, which seems a requirement, where in aft it doesn't. It also requires both clients to be on the same "Mailbox Server" to transit messages between them. Requiring a server by default doesn't seems reasonable only to omit IP addresses.

Each program has it's unique benefits, Magic Wormhole looks great, but I do believe that aft gives you more configuration by default, and its more accessible to you.

Also, some people like Rust more than Python ;)
