Feature Request: Error Correction.

I think it's really cool how this library has been used to create efficient communication, by the likes of Gibberlink and Waver. However, for the latter, I had an idea - what if there was error correction? For example, there could be an option to toggle a couple (user-settable) copies of the message being transmitted, instead of one. However, the real purpose would be to see if they match up and can be corroborated to produce reliable messaging over longer distances. I know this is just a demo, but i strongly urge your to consider this idea. Please?
