I'm not saying that. I'm saying the the protocol already supports
the transfer of authentication packets so it's just a matter of
extending things on both ends to get the server to authenticate
the client.

This has nothing to do with pool. The server shouldn't be in the
pool if it requires client authentication. In any case the NTP
authentication is NOT a function of the IP addresses. The MAC
section of the NTP packet is what is used to transfer authentication
