You are not getting an argument with me about that one. Here is a
varation. Make your first prototype alone. Then pair. That's how
to get 'make one to throw away' embedded in the creation process.

This is one of the principals of XP which we are stress-testing. I'll
let you know when we have done this enough to have any firm conclusions.
I came to XP with a background that said ideal is 'everybody has their
own office and we *also* have a shared terminal room. YOu get/give help
with anybody who is in the terminal room. We haven't tried that here,
but its only recently that we are enough people that it is a viable idea.
(Of course, we don't have enough machines to do it now....)

Don't formalise the process too much. You are not trying to bring order
to your establishment by building rules that work top-down. You are
trying to foster order that works from the bottom up. How any two
people best collaborate can vary with the people -- and if you are
on a roll you may want, need, and deserve a few days with each other
and only with each other -- otherwise 10 minutes, or an hour to
kill this one nasty bug may be enough.
The person who is doing the typing is in more control, but the person
who isn't is in a better position to exercise good judgement. This
usually works better when it swaps in units a lot smaller than 'a

And I from you, and I from you.
Have you read 'Engineering and The Minds Eye'? I just finished it.
