That sounds like a really great setup. I'm going to have to try this out one day. I've never really considered the specific benefits remote pairing would have over in-person pairing...generally the only things considered are the downsides.

Obviously, some of the things you mentioned with in-person pairing can be alleviated. At my current client, our setup includes multiple keyboards and mice. A friend of mine uses his own keyboard with a hardware switch to go between dvorak and qwerty.

You mention not being able to share a browser which makes me think of the times where it would have been convenient to look something up for a moment while my pair experimented (two pronged problem solving approach... :).

Also, what kind of pairing patterns do you use in this setup? Ping Pong TDD, driver/navigator, etc... ?
