I've seen serious problems due to unwanted interactions between TCP 'slow start', 'delayed acks' and Nagle (disabled) on zero-delay local networks with connections carrying uni-directional non-bulk traffic (ie relaying messages received on another network).

To ensure data is actually sent we had to send data in the reverse dircection at least every 4 ethernal packets.
