How to configure redundant radius?

[Christ Schlacta]

I have about 8 users, with on average 2.2 systems per, for a total of 
about 20 clients, but I'm setting up redundency because I've got 
basically two systems, both of which have fairly low uptime by 
enterprise standards, and downtime is met with much headache and 
griping.  Is there no other way to coerce these single-ip devices to 
work with a pair or more of radius servers, or no other way to configure 
reliable failover ?
