Ok, this may (or may not) help.

Have a look at http://www.nzstory.com/mac/default.htm This is the process I recently followed for doing something similar to you. To use it however, you have to download some software (via bit torrent) from http://www.mininova.org/tor/1280998

I'm seeding this at the moment, but I only have DSL and restricted upstream bandwidth.

If this looks useful, and someones got somewhere a bit more permanent to host it, let me know.

Cheers,
