Using John's approach you would have to worry about things like keeping track of each client session IP address and port number so you could support multiple sessions from a client and during the replay, send the proper input to the right (new) TN3270 session.
Your "transparent proxy" would also look to the TN3270 server to be the client machine (IP address of connection origin). This can cause all sorts of problems with how the server allows or decides how your client can use its services and what LUs are allocated to its sessions. And to build the screen image buffer from the 3270 data streams, you have to basically write a 3270 emulator. Agreed, these things can be handled, but I don't think this would be an easy path to do what he wants.
