Look up archives. A dhcpd load balancing solution is already described
and works wonderfully. Limited to two LTSP servers.

Why not build an application server for blender only?

The dhcpd load balancing does this.

If space is not a problem I would rather do a RAID1 mirroring with two
disks so that even if a disk crashes (more likely than a server) data
remains available and services do not stop.

PS: I know most of people do not follow email niceties (mostly they
are not aware) but if you follow bottom post/in-line post style of
email conversations it becomes a whole lot easier to carry on
meaningful dialogue and you can snip out what is not meaningful too.
Most people just hit reply button and top post leaving prior message
appended uselessly at bottom. See if you can adopt this style and
persuade others. In case you are already doing this ..... great,
spread the message.
