We are about to release a new version that includes integration with Amazon S3. Serve your files from Amazon and save big time on bandwidth. Read the manual page.
While our tests are all positive we would like see it "in the field" a bit before a public release. We are looking for Beta testers! The first five people to contact us will recieve a free 6 month subscription to MyMuse. All we ask is that you test out the S3 integration and report back.
