GNU Screen vs p2pmux

GNU Screen has no write-up on Specifiction yet; its figures are above.

p2pmux is a free peer-to-peer terminal multiplexer for connecting people and machines to one shared session. Each pane runs a real shell on the machine of the person who opened it, using that host's tools and environment. Shared sessions can have up to 8 members, 9 tabs, and 8 panes per tab, with nested splits. Terminal streaming is end-to-end encrypted and peer-to-peer, with an iroh relay available when NAT requires it. If the coordinator laptop closes, panes on other machines continue running, but layout changes and new joins pause. Processes and credential files remain on the pane host rather than being uploaded to peers. The agent inbox can show detected coding agents and open a pane for terminal input. Anyone with a join code or ticket can see every pane and interact with terminals; join codes last six hours. The project supports macOS and Linux, not Windows. Linux builds require glibc 2.35 or newer, while musl systems must build from source. It is released under the MIT license.
