ps shows how much is physically mapped within
a process, and reading /proc/pid/segment will
show you exactly where it is mapped.
the hard part comes when you want to figure out
the total for a set of processes, because figuring
out the intersection is not so easy.
for procs sharing memory, only the stacks are
different, and stacks tend to be only a page or two,
so as rob said, what's listed in ps applies to the
collection of procs pretty well.
