Where I work we use a simple version of Scrum. Following the sprint review at end of every 2-4 week sprint, each developer either gives a short demo of the new features or changes they completed or a short review of the most significant code changes they made. Those who focused on features generally prefer to give demos while those who focused on bug fixes usually ask for quick reviews of just the most important changes. In total these meetings can go a few hours but they only happen on average once or twice a month so they don't interrupt the daily workflow. We mostly just use our Trac wiki for reviews but I've been thinking of suggesting something like http://www.review-board.org http://www.review-board.org when we get bigger.
