They'll have to find a bigger stereo theater.  Height of ceilings in these
ballrooms can be a serious limitation even with the 7' screen.  Things were
tight in Milwaukee, I recall.  Figure the screen bottom at five feet off
the floor.  

The other problem is the throw needed to fill that screen.  Currently the
projectors are 50-60 feet away from the screen.  For an 11' screen, they'd
need nearly 90' of throw.  Add the 20 or 30 feet for projection platform
and accessibility to same and you've got one big room.  It's tough enough
now to find facilities with room.

Of course the biggest benefit would be that satisfied feeling one gets from
altruism.

90% of P-3D not attending the world's largest gatherings of stereo folks?
Looks like I've got a job ahead of me.  I'm expecting EVERYONE to attend
NSA 2001 in Buffalo.
