I'm a fan of side by side programming. This is where both people have their own computer. Both work on quasi-independent problems, but are free to ask the other questions and bounce ideas off them. Basically, stay far enough away in the code to not create to many merge conflicts, but close enough that you both can keep a mental model of your work and the others work. I prefer to share a whiteboard rather than a keyboard.
