I commend your worthy intentions, especially in making PPM's available that aren't available or up-to-date on the ActiveState repository.
And as a Scotsman, I also commend your correct spelling of "tightarse" - and frugality is indeed a virtue :)
Sorry I can't provide any pointers for your hosting question - one thing that would be nice (and may already exist) is an up-to-date list of PPM repositories.
