Hi!

Have anybody tried or considered to implement encrypted or
secure-hashed TCP-checksums of OTP validated connections?

This should prevent TCP connection hijacking with a minimum of per
packet overhead . The OTP validation phase should be enough for
"synchronizing" the endpoints?

I heard somebody suggest this once but I've forgotten whom.
