I just remembered having a similar problem and how I solved it. I added a fixed 
IP for the machine at the end of the tunnel in /etc/hosts, and the fixed IP was 
127.0.0.X, which seemed to allow a unique entry in known_hosts on the 
originating machine. Since all of 127/8 is used for loopback, I decided to use 
another address for the made up machine name.

You still have to edit /etc/hosts for each new machine, but once and only once 
per machine.
