In case you have not noticed already, Auphonic now supports Amazon S3 and Archive.org as external services. Archive.org, also known as the 'Internet Archive', is a great service for publicly hosting audio and video files for free. Amazon S3, on the other hand, provides both free and affordable services for public or private file storage, featuring better download speeds and high durability. S3 also interfaces with Glacier, Amazon's cheap solution for long-term archiving and backups of data that does not require rapid access.
