The setup I've found works best is to have two computers with browsers pointed to an Etherpad document, to allow pseudocode, and use problem domains that don't require the use of references.
That allows face-to-face communication, and avoids the uncomfortable violation of personal space induced by over-the-shoulder glancing.
Incidentally, this technique scales very effectively for phone interviews.
