Canon VIXIA to Macbook to Skype

Does anyone know the best inexpensive way to get one of the Canon Vixia pictures into a Macbook then through Skype for a poor-mans streaming alternative? I take it the HDMI output on the VIXIA might be the answer, and they might use a separate audio input going through a more professional audio system. It's essentially a teaching/lecture session in which they need the throw of a more telephoto lens than can be had from a webcam. I looked at Dazzle as an interface possibility, but am wondering if any of you have used some alternatives for a system that would do this? Thanks.

So I take it one can simply use a HDMI to Thunderbolt adapter cable to get the signal in?
