1. Your reply was "SYN cookies can be a solution, but it has limitations, and to overcome those limitations requires changes to the TCP protocol." Can you tell me more about these limitations? I thought the SYN cookies work pretty well. And they are pretty simple to setup -- in fact, they need no setup at all, as they are already enabled by default in the recent distributions.

2. Right, so how does your protocol solve a padding problem? Why won't this method work with ZeroMQ?

3. As I was saying above, this is still wrong. Both TLS and CurveZMQ are protected against replay attack.
