Hi there ... I've waited for this feature for a while. I'm wondering if you have any agreement with AWS for caching live streaming using a CloudFront CDN and Wowza instance as origin.
As http traffic, caching should work just setting it up as http download and using wowza as origing, but Cloudfront has specific ways of setting their CDN when you'll do live streaming using Adobe Flash or IIS7 smooth streaming. They say it's an improved pre-configuration they have created for better performance.
I'm wondering if something like this exists for Wowza
