there's a rather large misunderstanding on its github page:
You can't use openssh's PermitTunnel feature because it's disabled by default on openssh servers; plus it does TCP-over-TCP, which has terrible performance.
it doesn't do TCP over TCP, it's a bytestream over TCP (exactly the same as shuttle)
something like OpenVPN running in TCP mode would be TCP over TCP

SSHuttle was created by the CEO/co-founder of Tailscale :)
Indeed, both the name and the very clever combination of existing components sounded familiar when I first heard about Tailscale :)
Interesting. Sshuttle is great. I've used that a couple of times to create a simple vpn without having to deal with openvpn. Simple and effective.
that's a bit worrying

Are you sure you are not misunderstading PermitTunnel yourself?
That SSH feature is indeed used for packet forwarding over SSH using TUN/TAP, i.e. packet-over-TCP, and by extension TCP-over-TCP.
