Another option for using a CDN that will let you maintain better control and outage visibility, is to sign up for a paygo CDN account yourself. GoGrid and Speedyrails resell Edgecast CDN and Softlayer resells Internap CDN both of which are very good performing CDNs with both origin and pop pull models. The cost for these services would only be about $0.57 per 100k jQuery hits (assuming 24KB minified version is used).

One of the biggest underlying benefits of using a shared, public CDN for this is that you can take advantage of cross-site caching. As more and more people use it, the potential for that is greater and greater.

However, it only works if sites are referencing exactly the same URL; just referencing the same file is unfortunately not good enough. So, using private CDNs like those don't confer quite the same benefit (though they're a great idea for hosting site-specific assets, of course).
