The always used example is to have /usr shared as a read only NFS
partition among several workstations. In corporate environments it is
certainly used this way (or at least it was when I worked, and the way
I used it in my office seven or eight years ago).
Of course, for a normal desktop user, a separate /usr is basically useless.
