Built on top of Fowl, shwim uses tty-share with localhost-only network addresses over Magic Wormhole (via Fowl) so you get durable, end-to-end-encrypted, on-demand terminal sharing.
The host types shwim which prints out a magic code, and the guest side types shwim <magic-code>. Now both sides are typing on (and seeing output from) the “host” machine.
The tty-share project hosts a public service – however, while traffic to the server is encrypted, it can see all content. Also, if you sleep your laptop or disconnect briefly, the connection is gone.
Using the “magic” of a Dilated Magic Wormhole we can easily layer “durability” and “end-to-end encryption” on top of the existing tty-share program (with zero changes to tty-share itself).
We say a connection is “durabile” when it can survive interruptions and inconsistency while remaining invisible to the application protocol (i.e. tty-share in this case). Magic Wormhole will re-connect on changed IP addresses or other network conditions, correctly resuming the flow of bytes for tty-share right where it left of – it can’t tell if you simply didn’t type or 10 minutes, or re-located to the coffee-shop.
