Hi William, Thanks for your message. This is definitely the nicest "why I switched back to SSH" note we have ever gotten. :-)
You may be interested in our conversation with the iTerm2 folks earlier this year -- please see https://www.mail-archive.com/[email protected]/msg00304.html The scrollback is on the agenda for us; unfortunately I doubt the integration to a native terminal emulator is going to happen anytime soon. You could get somewhere by just running tmux locally (and maybe having it automatically run "mosh server" when you start up a new tab), but I realize that's probably not quite what you wanted.
