"different sessions, browsers and even computers can be used to access clipboard contents"

Right, and if ID theft is involved, then your data on the cloud can fall into the hands of God only knows.

All that risk from a simple copy/paste.
Thanks Google, but I'll pass.

come on - does the author have any insight into whether it's easy or even possible for a javascript page to communicate with the system clipboard? _that_ would make some interesting commentary, rather than snarkily impugning the programmers' knowledge.

But why can't someone create a way to encrypt and decrypt cloud storage on the fly? Store your information encoded and have it automatically decoded as it comes back. So your porn wouldn't be porn unless the key was known, if the key wasn't known it would just be a large file with seemingly random bits thrown in. You could do this will email too, make an email program that associates different email addresses with different keys.

I'm guessing someone has already had this idea, so let's find them and tell them to get off their ass and get this out there.

Not that different to the normal clipboard though, which also doesn't automatically clear if the original document is deleted. Google do provide a way to clear it manually too:
"You can delete all items stored on the server clipboard by clicking the drop-down menu and selecting Clear all items."
