My thoughts are:-

NFS is fine if the content is not changing often. As it is a single
point of failure, you have to have a backup and do all the failover and
synchronizing stuff mentioned in other emails.

With a distributed file system, this is not the case and it 'should'
sort itself out as servers go offline. This system is needed if you have
dynamically changing content which changes often, then rsync will not
cut it.
