then maybe you should have said something along those lines earlier, instead of repeatedly asserting that s3 and dropbox are equivalent (and then asking if you'd missed anything).

Do you read carefully? When I asked if I missed anything I was referring to anything besides the arguable "value add". My apologies if that was not clear. But the value add is precisely what you focused on, and argued (predictably): the python, rsync and the icon. I'm asking about the S3 component.
