wemux enhances tmux to make multi-user terminal multiplexing both easier and more powerful. It allows users to host a wemux server and have clients join in either:

Mirror Mode gives clients (another SSH user on your machine) read-only access to the session, allowing them to see you work, or

Pair Mode allows the client and yourself to work in the same terminal (shared cursor)

Rogue Mode allows the client to pair or work independently in another window (separate cursors) in the same tmux session.

It features multi-server support as well as user listing and notifications when users attach/detach.
