Google is now hosting Javascript libraries.  All the popular ones (JQuery, Prototype, Mootools, etc.) are there.  Since they are hosted by Google on Google's servers, and since we can not modify them from their original release status, can we please link to this on the profile and home surfaces?

We have been evaluating this as well and will be allowing external libs thru google's shares.  It hasn't been officially announced because we are working out some final details with the app review process, but look for a blog post on this soon.
