Migrate all user processes onto a different box,
shut down,
repair or replace,
bring up,
rejoin cluster.
Given migratable tcp-ip connections
http://tcp-impl.grc.nasa.gov/tcp-impl/list/archive/0696.html
this could be done transparently.
Without, another host could set up a bochs/vmware like
environment to contain everything the computer that is
in need of repair is running, and it would be activated at some
"instant" the same time the NIC on the host host starts
listening on the broken host's IP address and routing those into the VM.
