I accidentally tripped across Part 3 UncleCheese's Uploadify tutorial (here: http://www.leftandmain.com/silverstripe-screencasts/2010/08/25/uploadify-tutorial-part-3-amazon-s3-integration/), which mentions S3UploadField and S3MultipleUploadField for integration with Amazon S3.
I need to use this or something similar in SilverStripe 3, but I can't find any mention of it anywhere other than that tutorial, and searching the Forum and on Google is turning up nothing.
Can anyone point me to documentation for S3 integration for file uploads, including where to get such a module for SS3?
Thanks!
