But the point about academic workloads is that often we use every desktop in the department as
a distributed supercomputer, so the nodes are both exposed to every possible attack because
people want their desktops accessible from outside (at least via ssh) and want to be able to
surf the web, and may be running background jobs for weeks at a time belonging to other people
who don't want them to be restarted. The conflict between these two factors is where this kind
of technology becomes important.
