Are you willing to play Mallet? Drop IP packets, and look for duplicates. Those are TCP. (IPSEC might handle this, but I bet there will be broken implementations that save time by resending.)
Are you saying UDP protocols don't retransmit un-acked packets? If not, then you can't be sure the duplicates are TCP.
