You can see how desperate I am for help by the use of the second word in the title of this post, which I’ve resisted until now.

I have offered to present a talk to a large conference audience in Adelaide, and intended to do it by videoconference, following several successful (and cheap!) presentations to seminar-size groups. But the conference of organizers have been quoted a cost of thousands of dollars to present the videoconference session. There are some obvious cheap alternatives like a pre-record, but I’d like to avoid these if possible. Does anyone have any suggestions as to how I could deliver a videoconference presentation, at reasonable cost to a large audience in a venue that isn’t specifically set up for this?
