Perhaps you don't recall how we got into this discussion. We were
talking about whether or not the server's address belongs in the UDP data
payload. My position was that it belonged there. You said that the server's
private seed could serve the same purpose the address would serve. I argued
that it would not.
Somehow you concluded based on this that I had some issue with the way
the hash was managed. I have no such issue. It is perfectly designed to
serve its intended purpose. However, it does not obviate the need for a
common unique identifier for the server, akin to a public key.
