ok here is my idea right: most cloud variable projects that involve say live comments have a fatal flaw. impersonation, see if i was evil i would use websockets to set the cloud variable to whatever i want and people would think hat a server sent it and woudl tihnk it was real. basically digital signatures. So we have two functions GenerateSignature(message, private_key) -> signature and VerifySignature(message, public_key, signature) -> bool. We can make the message store time data to avoid weird repeats and now nobody can impersonate the server.
