I was puzzled by this, as well.  However, I know that I often
talk to a machine "on my left" while logged into a machine
"on my right" (i.e., separated by a few feet).

I can see the possible rationale behind not recognizing
hotplug events *initiated* by the "remote" user.  But,
can't see why the OS would refuse to recognize the
introduction of a device regardless of whether someone is
logged in locally, remotely or NOT AT ALL!
