Trying to fix the internet protocol at the application level is a hack. You should check out the 'Host identity protocol'; that's what you're really looking for (fixing the internet). Beside, splitting parts of the code between 'server' and 'client' does not keep anyone from running the server along with the client.
That's all nice and fluffy sounding. Anyhow, I'll sell my share of the beaches and take the cash. What? I can't? Then this whole story is one giant bull shit. If you can't sell it, you don't own it.
