Environment variables can probabbly be used to determine that the module is just being used for automated testing.

Please announce if you've found a way to do this; I was under the impression that you can't tell if you're running on a CPAN smoker.

For what it's worth, I would also like to get feedback on how widely my CPAN modules are used, but would prefer to see a community-wide solution, such as patches to CPAN/CPANPLUS and a shared site to collect the stats... That way we get stats for all modules, not just a few of them, and people can opt in or out of the reporting process in a central place, rather than having to sit there watching the build process and hitting control-C to interrupt the logging requests.
