Summary
Right now with LTSP in ubuntu there is no good solution for using more then one server for thin client deployments.
Rationale
Use Cases
A real life scenario is our thin client deployment at the school of Engineering at Oakland University. Initially, we had Sun Sunrays backed by the Linux port of the SunRay services. Since then we've moved away from SunRays to real X11 terminals based on LTSP support in Ubuntu. Some of terminals are dedicated X11 terminals that were purchased at the beginning of this calendar year other terminals are desktop machines that can be booted into "thin client mode" via a PXE boot menu.
The one feature that was lost in the transition from SunRays to LTSP is the support for multiple servers. Right now thin clients all run of of one server, out of the two available. This summer time the school of Engineering is getting three more servers. Here at the university a lot of the applications that our users run are engineering applications (math, physics simulations & CAD) which tax the systems, which is why we need multiple servers and the ability to grow vertically.
