Last week an adjunct professor approached me about a presenter for his evening class who was in New Hampshire and could not be part of his panel. This presenter would be at home and did not have access to videoconferencing equipment. I suggested that he may want to try SKYPE.
I created a skype account (albany.law.school) for us and he downloaded the software onto his laptop, used his cell phone for Internet access and we tested it.
I hooked up a microphone to the laptop in class, connected speakers and projected it onto a large screen and for over 2 hours, this presenter from New Hampshire was LIVE!! It worked like a charm and cost nothing!! Everyone in the room was impressed.
