Mishkin Berteig pointed to this web page about setting up a team room. This page pretty much covers everything I have in mind about the subject, especially with the links it has. Pros and cons of the team room are handled. These guys also share my philosophy about forcing these things. If you should force people to do anything, team room and pairing are definately NOT among such things. I believe these issues are automatically brought in when (if) the team jells and learns to work together.
