Sure.  They even reference DIVE, and DIVE was around before that (not
to mention the other research projects and military systems that
weren't referenced) and had some similar things if I recall correctly.
There's a lot of prior art to be had, as well as some alternative
approaches that are probably superior to what they've listed in some
of their claims for limiting users displayed.

It is still a potential nuisance though and would require money, time
and effort to challenge.  All of which is a shame if you're either a
small company or a freely run system.
