I know this is hard for security and dozens of reasons, but the thing that drives me nuts about mosh is not having SSH's ControlMaster protocol so I can multiplex. It's a protocol thing, so not directly fixable via a compatible implementation. But it just sucks, I have so many tabs, and I have each one having to do the deed again, maintain it's own connection.
