LTSP seems perfect for horizontal scalability.  And HA would not be
too hard, too, using something like http://www.backhand.org/wackamole/
to share a pool of IPs across a cluster of LTSP servers.  Need a fast
switch for the pool, of course.

Granted, if a machine fails a client would need a reboot, but dhcpd
would not need to be reconfigured.  Kind of handy to be able to just
plug in a new server and have it start working and sharing the load.
The risk is a machine or two might die overnight and you would never
know it was down. ;)

Of course, one of the benefits of LTSP is to not have too many
machines to manage.
