We did exactly this for the two-month sprint for the initial code for Dawdle. I moved into the contracting firm's office, and we did this stuff all day long. It was great; they got a sense for what was "nice to have" and non-negotiable and I traded stuff that wasn't as important (a functioning search; we ended up using SWISH-E, shudder) for stuff that was (user account management). Both sides learned a lot, and I now know that most programmers aren't as good as the people who did that code. To this day, two years later, our search still sucks, but the basis of that user account management has meant that we haven't had to touch that code in almost two years.
