I'm not aware about how to request a space in a PPM repository

In the general case, if Activestate are able to build the module, it will be made available as a PPM package, following the same namespace layout as CPAN.

On the rare occasion that the module is not available in the AS repository, Randy Kobes's unwinnipeg site usually has it available (see link elsewhere in the thread). The other repository that cover the bits and pieces left over is Trouchelle.

Basically, though, if it's pure-Perl, Activestate will carry it.
