You are basically adding an address to TCP (the UUID) that names the host... Moreover, what happens if the connection fails during setup? A lot of edge cases here.
I am also removing the remote ip address from a socket. Hence, if you change your ip, you can just send from your new ip, include the same connection uuid, and I will still receive. You'd also need to know how to send data back. This could be done in many ways.
Biggest thing is to deal with really easy hijacks where you tell a server that your victim 's data should instead be sent to you. This is harder with the current TCP.
