I suppose scripts are no different from other resources on the web, so they can be cached even locally at the browser. So in principle, there shouldn't be a need to pull down the same script from the same site over and over. But as far as I know, caching is based on URLs and not URNs. This means that even if two sites were using the same library, caching wouldn't notice that, if the URLs were different. I don't know if there is a solution to this (other than actually sharing the URL , which might not be practical). It would be interesting to learn.
