We use Github, iChat (but have been using Google Hangout more), Campfire.

I'm a remote worker, so I have switched to tmux + console emacs (some guys prefer vim). That works much better than ScreenSharing and a typical GUI editor.

I've checked out wemux, but it didn't solve my pain-point which was the ssh setup at the remote end.

The bigger deal is not whether your team has the tools. But whether they use the tools. Co-located people may talk in campfire/irc/group chat, and some may not even log in. But remote workers depend on it.
