the lab I was at got on this train right around the beginning of the sparc architecture. yellow pages. nfs based swap, nfs based boot. 10Mbit thinnet. we suffered for a few months and then moved to xterms for the cheap seats (which was a much better place to cut services) and went back to buying self-sufficient workstations.

the best was having everyone with a disk cross-mount each other. any failure snowballed into a global failure.
