s3 video audio streaming

I would like to set-up a Drupal eCommerce website using the latest stable versions. It will be a CD store to start then I'll gradually add modules & functionality to builds a whole vibrant community around this niche Dance market that we serve. I've been in this business going on 29 years and we have some unique things that no one else does. Our customers have been asking for a website for years now, but we just haven't wanted to take the plunge, but we're ready to move this project forward one step at a time.

For my information, can one have a decent streaming speed from S3 servers? Our material is mostly going to be audio and video. Thanks
