What sort of changes did you have to make?

We're planning on doing something similar with Sun Cluster. Why Sun 
Cluster? Well, it's the only cluster environment that WebCT supports, 
and managing two completely different clustering technologies would be a 
bit much for our little brains. ;-)

Not planning on doing anything particularly sophisticated. Just failover 
when one node fails.
