Sure, technically a generic TCP proxy in the way you described could 
handle AMQP. After all, AMQP travels over TCP. However, what David and I 
have been trying to point out is that *semantically* that makes no sense 
at the AMQP level. Two AMQP brokers when fed with the same input data 
stream will *not* produce the same output data stream. Not even at the 
level of a single connection, let alone when multiple connections are 
involved.
