I don't understand why people have a problem with this. It's sleazy, sure. But clients should never trust the network. The fact that this is happening is due to protocol and software faults that need to be fixed. Once your network client can no longer be fooled with rubbish inserted by someone who happens to own some wires, then fake responses become a simple matter of bandwidth and QOS agreement, like dropped packets. The fault here lies with the developers of insecure network client software.
