I agree that "if they ever release it" is a powerful point against screen. Is tmux actually better in that respect? I feel like your critique of screen's customization is a little inaccurate; you said that "screen only lets you change a few of the bindings," but actually, copy/paste are the only ones it does not let you change. I agree that they're rather unintuitive. As a vim user, I have less cognitive dissonance, but I do dislike the way that the bindings are almost vim. I think you did yourself a disservice, though, by never figuring out copy/paste at all--it's quite usable once you get the hang of it. I think that hand-wringing over using suid for shared sessions is premature; while I agree that any experienced sysadmin should flinch at the overall concept, it's important to remember that the screen binary itself is still writable only by root, and that while you run it with setuid, the resulting shell child process is not run as root. So, to the extent that there are no "screen injection exploits," running it with setuid is a non-issue.
