ncomputing.com does not condone the use of "single" license on one server and then connecting them..
so using one windows license for ncomputing 'might' not be legal....
when ncomputing units are "damaged" nothing can be salvaged..
when pcs are broken.. they are easily 'repaired'
ncomputing devices are relatively expensive.. L100s cost around 12-15 thousand right? thats about the cost of an elcheapo system (which can be made to run pxe/thin client solutions)
just my 2 cents... i was also evaluating ncomputing stations as a solution to my training labs.. it turned out more costly(for me, just my personal opinion) than implementing thin client off the shelf setup..
