Tom,
We use Rackspace's Cloud Files for Cloud Server backup, not CDN, but it is built for that. You can use it with Akamai to serve content. It has versioning and mobile UIs:

Is anybody out there using a CDN[1] that is separate from their website to
host JavaScript, CSS, and image files? I'm looking for a one place where I
can consolidate and organize these files that is reliable (good uptime and
good response time) and affordable (less expensive than hosting a complete
website). In-as non-technical folks may need to access it, the interface
for managing the files and directories needs to be friendly. E.G., AWS's
native interface is too convoluted for newbies, but a program or web app
built as a front-end designed to have simple management functions is the
kind of thing I'm looking for (and something that mirrored AWS's built-in
versioning would be awesome).
