Yeah, I remember there was a service like this around 2009 (that, like this, I thought was pretty nifty... I wish I could remember the name) - but it was anonymous and you didn't need auth: you could write to a url and have the hash of it as the "read" endpoint... I used that for a lot of quick mock-ups and things.
