known_hosts(5) man page

[Dave Yost]

Here's our situation. Two hosts, s1, s2, each with its own key.

Domain name foo is aliased to either s1 or s2 (each with its own 
fixed IP address), depending on which is working correctly at any 
given time.

The known_hosts(5) man page, when it comes into existence, should 
explain how I would express that the ip-address/key pair from either 
s1 or s2 is acceptable when connecting to foo.

I can't find any documentation that suggests if this is possible or 
if so, how to do it.

Thanks

Dave
