I'm using SVN with Google Code Project Hosting for a school project. As the codebase increases in size, I often find myself wondering questions like:

• "who originally checked in this line of code?"
• "who has been checking in the most code recently?"
• "Of the final product, how much of it was written by Person X?"
• "Which coder is best at adhering to the coding conventions?"

Is there any plugin available to do this? (If not, I would be interested in developing one myself. Any ideas on where to get started on that?)

We're using Visual Studio 2008 with the AnkhSVN plugin.
