I also waited for cpan-smoking solution in a box to start testing my modules. However, at last YAPC Europe I was enlightened that whole purpose of testing is to have your own different test configuration, and not yet-another-copy.

This somehow makes perfect sense to me, since most valuable test reports are from different machines, not from different version of same testing environment.
Somehow, I also promised to make CPAN testing site on qemu-neo1973, which I still didn't do :-)
