At first glance it looks something like Dropbox with S3 as the storage backend. They suggest it being used to keep files in sync between a standard PC and a WorkSpace. I wonder if it can be used without the WorkSpace?

Edit: Actually this isn't the dropbox functionality. For that you'd have to wrap it in an inotify loop:
"while true; do inotifywait -r -e modify . && aws s3 sync <local> <s3 bucket>; done"
