Does the practice of sitting together mean that multisite teams can't do XP? The simple answer is no; teams can be distributed and do XP. Practices are theories, predictions. "Sit Together" predicts that the more face time you have, the more humane and productive the project. If you have a multisite project and everything is going well, keep doing what you're doing. If you have problems, think about ways to sit together more, even if it means travelling."
