Setting up a CDN and have Subsites be able to use it without User Actions

The title says it all Setting up a CDN and have Subsites be able to use it without User Actions
I have been slowly Migrating some of Our WordPress Blogs to use Amazon Cloudfront CDN
I'm looking to do My Multisite Blog to use it and Read that sub Blogs need to have them setup separately with another Cloudfront Distribution.

I also read Cloudflare is the same but there is a plugin that adds the sub blog to the main account.
Thinking that might be the way to go unless I can do the Cloudfront automatically.

This is a question for @WPCDN - Your Service -
Does it do Multisite automatically like I need above?
What locations are you Servers?

Could someone let wpcdn Know there is a question for him I couldn't find here

thanks in advance
