Hm. I think it's going to turn out to be useful. Experience shows
depending on the ip address often paints people into corners. However
I agree that we need to actually have a real use case in hand where
someone is going to actually do something with it.

My question is a bit different. How does this interact with TLS SNI.
Can you just use the SNI name given in the TLS handshake? Should the
server require them to match? Is there any value to having a separate
source for this info? Is something similar available in GSSAPI
authentication?
