Recommended approach for integrating a CDN with a Craft site I realize there are lots of options out there, but I’d be interested to know what service folks would recommend for integrating a CDN with Craft?

It'd also be helpful to know what the general pain points, strengths and/or weaknesses of a given approach are (especially as it relates to Craft integration).
It's extremely easy if you're using a pull CDN like MaxCDN or KeyCDN. You just point your CDN at your server, and then point your Asset Sources at your CDN.
