If we do put all the upstreams packages on github (and I'm not saying it's a bad idea), it would probably make sense to put them in a separate repository, and include it as a module. That would make it easier to kill old versions in order to save space.

As for making it possible to build offline, I think that could be achieved simply by skipping the invocation of "wget --continue" when the file already has the correct size. We could create a download script that's a little smarter than just doing wget blindly.
