It's usually done with a single computer. Sometimes shops will have multiple keyboards hooked up to one computer. But it doesn't have to be that way. There are lots of tools for pairing remotely. Screen/tmux + Vim/Emacs, Screenhero, Google+ hangouts, etc. I don't want to toot my own horn, but at Floobits (YC S13) we've built some really nice tools for remote pairing. I like Sublime Text. Bjorn likes Vim. I live in SF. Bjorn lives over in the east bay. But we pair using our native editors: http://abughrai.be/pics/screenshots/Screen%20Shot%202013-12-04%20at%205.46.37%20PM.png http://abughrai.be/pics/screenshots/Screen%20Shot%202013-12-... We're still improving the setup process and documentation, but we've found it to be better than pairing in person. We get to use our favorite editors. We don't have to commute. We can listen to different music while pairing. It's pretty nice.
