Lots and lots of cluster-related software currently requires IPv4 so I suspect 
that this would be a challenge.

One thing IPv4 makes hard (for most people) today that IPv6 will fix is to 
"afford" assigning global addresses to all nodes in a cluster (even though 
most people can live without that...).
