Well yes it exists, however it's too high friction IMO for me to use - and I'm already a software guy. And I mean the data at the application level too - it wouldn't be practical for me to have to keep removing apps and data since they don't integrate with this at an OS level and with your proposal we would have to manually sync/remove data from S3.

Or I suppose we would program something to make this. Just saying, doesn't exist today it seems but would be valuable for us.
