Code Collaborator (Score 1)

My company, Smart Bear Software, has developed a commercial tool for peer code review called Code Collaborator. We support a wide variety of SCM's, including CVS, Subversion, Perforce, Clear Case, and soon Team Foundation Server.

Using our tool, we also performed the largest case study of peer code review ever published and have made it available as a free book. It includes data from 2500 reviews of 3.2 million lines of source code at Cisco Systems. To get your free copy, just sign up on our website.
