I'm really glad remote pairing is getting such inventive attention lately. I have, however, been a little disappointed that the mode of collaborating that I prefer doesn't seem to be well supported.

Many people can't or don't want to grant login access to their local development machine in order to share a screen/tmux session and using a mutually accessible machine means leaving behind or laboriously duplicating the local development experience.

I've used hacks to get what I want (https://dev.launchpad.net/yellow/RemoteTerminalBroadcasting) but I haven't found anything truly satisfying yet.
