Absolutely nothing else we do with it ... it just gives us a unique key
to work with ... in fact, assuming each of your servers use a different
IP, there is no reason you couldn't do the uname trick above to hide
the  hostname ...

Unless someone breaks into the server, or database, somehow, the data
isn't accessible ...

What if we improved upon this - if instead of storing the hostname and
IP address, we stored a one-way hash of this information? OpenSSH in
recent versions takes the same approach with its authorized_keys files...

I like that idea. I'm ready to submit my workstation, but I'm still a bit hesitant about some servers I admin....A one way hash would alleviate my concerns.
