(If I understand you correctly) What you are talking about is interpolating based on past data, but interpolation doesn't work for this situation in practice.
An example: a successful copy from two years ago was ONLY successful because it implicitly referred to (then) current events, and with that missing context it would be irrelevant today.
I'd go with any result on Google for "collaborative text editor". setup a public pad, write your text, delete it. and you're done! it's likely they don't even save history, but who knows. free, anonymous, literally instant messaging.
