hmmm.. I just restumbled on this thread. How about some RCS stats?

I ran gitstats over the codebase, this is probably one of the most interesting graphs I saw. It show the most prolific coder per year (at least as fas as commits go, so don't read *too* much into it, e.g. I've personally done a lot of Coverity commits rather than awesome sauce feature commits), and the number of contributors per year which you can see has remained fairly stable since the SCP started.

And here's some author stats as well:

If anyone is interested, here's the full set of stats. It's in html format, unfortunately I don't have any convenient way of hosting that in an easily viewable form.
