Are these "real" xterms or Linux boxes just being used as xterms ? If
they're real xterms then there's only a kernel to be downloaded, as xterms
themselves do not mount filesystems, nor does their boot process involve
running god only knows how many binaries, so there isn't that big a network
load. Of course, the change from 10Mb to 100MB networking helps too - that
would have made the worst case in the Maynooth example be 3 minutes, which
wouldn't have been too bad, and of course it gets even better if you've got
a switch with 100Mb ports for clients and some 1Gb ports for servers. Of
course, the scenario I spoke about was a bit before 100MB networking or
switched Ethernets were available.
