A while back i had the idea of using Amazon S3 and EC2 tobuild a large podcasting and Video casting network. Well, part of this has been built (not by me, mind you) and proves its posible! Its called Mux and it transcodes video into different formats. definatly a step closer to the idea of recording a video cast, uploading to the web in one format, and EC2 generating different versions of it for distribution.
