James, thanks

Remote control was a serious question and after you pointed me out to
"Collaborate" I investigated it and found that Acrobat Collaborate
really gives such an option. I tested it (albeit without Skype as a
voice carrier as Skype was not installed on the resident PC in our
seminar room)


which gives a real opportunity to give a talk from another location
(normal video stream does not have high enough resolution to see
beamer presentation or blackboard writing without efforts).

What I am interested now is different: once a year my wife runs award
ceremony for school kids in some math competition in the room filled
with 250 of them and when she calls someone simultaneously we display
the name highlighted. She wants to push reading names to computer (so
if name is not called properly she could blame "the stupid computer"
