I wish there was a standard package management protocol. Why does every language have to reinvent package management? They could still write the package manager clients (and servers) in their language, as they all seem to love to do.

We (the ServerJS pseudo working group: https://wiki.mozilla.org/ServerJS) are currently looking at package management solutions for server-side JavaScript.

Using Rubygems with other languages like JS is one possibility, then we would get the Github integration for free.

And there's JSAN (http://openjsan.org/).

Kris Kowal hacked together one that pulls zipped repos directly from GitHub (or potentially any HTTP server) (tentatively named "tusk", implemented on "narwhal": http://github.com/tlrobinson/narwhal/tree/integration). One neat thing about that is you can create new versions just by tagging.
