S3Bubble is a wordpress plugin that will allow you to stream audio and video directly from Amazon s3, sign up for a account at s3bubble.com.
Plugin i use this for all my audio and video streaming love the fact if links with my Amazon s3 account allowing me to reduce high streaming costs that occur on my server.
The author seems to have picked up development on this plugins which is great.
the plugin is beautiful but inconsistent. problems with the data feed from data.s3audible.com. works for a time then your looking at an empty widget. no playlist, no sound, no nothing. very frustrating.
