limitation really only applies to programs listening for a connection.
 That is, you can't have more than 64k different listening sockets at
a time.

You're incorrect.  In order to open a socket connection you need a source port and a destination port.  So you as a client open a port in your 65535 ports (usually an arbitrarily high number) for receiving communication from the server.  TCP multiplexing is still involved with receiving server communication on a client.  Short answer is yes you're limited by the combination of listening sockets and receive ports for data from server to client communications.
