Nothing at my current position, but on a previous team we had a rigorous code review policy without a tool (FishEye/Crucible, etc) to facilitate it. I wrote a bash script that accepted a ticket number as a parameter. It scanned SVN for all commits associated with that ticket. For each file, it would diff the original version with the last version committed against the ticket, and pop the diffs up sequentially in Vim (IE, one end-to-end diff for each source file). I'm sure there's a better way, but this worked well enough at the time.
