Got it. However, I was thinking the initial file (ppmx) would essentially be a stand-alone download, the installer would then revert to the predefined repos to download the prerequisites. In PPM's case there are only a few repos that try to keep up with CPAN, so knowing where the original repo was may be significant. However, if we're downloading from CPAN, then it would be reasonable to try and grab prereqs from a predefined set of CPAN mirrors.
