For sure, the distance between that connector and the LCD projector on the roof must be more than 15' - 20', but maybe there's some kind of 'repeater' or 'amplifier' there. Next time I'm in the lecture theatre I'll spend some time after the lecture investigating what type of arrangement they have and post my findings back here, unless you get another reply before then.
