Not many people realize that if they are using a good projection screen during their presentations, they can actually bounce the projector's remote control IR signal off the projection screen surface - you don't have to aim it at the projector in order for it to work. This trick works from a standard distance of less than 15 feet, but with a distance of around 25 feet it may or may not work. The ability to bounce the IR off of the projection screen gives you a lot more freedom to roam around the room.
