OK, but what about setting SSH to use HostbasedAuthentication or
RhostsRSAAuthentication and have ssh_known_hosts which contains keys for
all nodes distributed to all nodes in the cluster; then you can make a ssh 
connection from any node to any node, so the scout scheme should work.
I do have here a non-SCore cluster that is configured like that - rsh is 
no longer installed.

The idea above doesn't use ssh-agent. It's just ssh on client side and 
sshd on server side.
