Still use a key, but don't force it to match a "" or
"" file, check against a list of known keys and if
it matches one then allow it; or use the name as sent by the client to
match the key instead of the IP/name at the other end of the socket.
Basically I just want some way for known hosts to use an unknown IP.

It's kind of scary to open cfservd to the world like this, but it's
scarier to allow wandering hosts to go long periods without updates. :(

Right now I make outside dynamic hosts establish a VPN, and once using a
known private IP on the VPN all the cfengine key exchanges work. This is
fine on a small scale, but since cfengine has its own key exchange and
encryption I don't need the benefit of the VPN, and I'd like to go
without it.
