[AG-TECH] physical security

Our original node was (and still is) in a public area.  While we didn't have
the problem of equipment walk away, our biggest problem was that everyone
and their mother would twiddle with it when it wasn't in use.  It would
usually take us about 30-45 minutes to re-align our projectors/color temps,
mics, chairs, cameras, etc before each meeting.  The other problem that we
had was the distraction of non-meeting participants walking by during
meetings, talking, stopping to watch, etc.  This usual caused considerable
amounts of background noise, as well as video blips from large, fast pixel
changes in the cameras.  Not to mention non meeting people complaining about
the volume from the AG disturbing their work.  All in all, a very difficult
environment to work in.

I completely agree that this is problematic.  However, with properly
planned dedicated space, a public AG is possible and setting up a few
of them in public spaces could be an interesting demo.  Imagine random
walk by conversations between folks at nodes set up in common areas.
Or between a pair of museums as part of a technology demo.

Setup considerations:

  Use security style cameras.  Mark a spot on the floor for people to
  stand.  Make sure windows show local video.  (To be really cool, tie
  them to a tracking wand like they use in hospitals for directional
  lighting.  The only place I have seen this is in Labor and Delivery.
  Wand would need to be secured somehow.)

  Rear projection system with glass/plastic over the projection
  surface for protection.  This protects the projectors and computers.

  Ceiling mounted mics, or directional mics pointed at the camera
  focal point.  There are probably more clever ways to approach this.
  Lots of science museums and even some playgrounds use acoustical
  tricks to carry sound from point-to-point without mics, and
  eliminate background noise.  You could make one point the camera
  focal point and the other behind the screen, placing the mic's out
  of reach.

  Touch screen for venue navigation.  or to keep it simple, just tie
  the system to one venue.
