Live Lecture Technology I am trying to come up with a method to live broadcast my lectures to parties connected to the internet.  Up to now, I have been using FaceTime to transmit my work on a whiteboard.  This method works, but the quality is lacking.

The crux is I do not want to record "my person," but rather what I write on some surface.  This previously asked question (Device for writing a lecture with a stylus for video lecture recording) solves the problem for non-live transmission.  That is, for the previously answered question, the individual records and subsequently uploads the lecture.  I would like to do something similar, but live-transmit the lecture.  Does anyone have a reasonable method by which they do this?  

My ideal solution would be something like an interactive pen display (e.g., http://www.monoprice.com/Product?c_id=113&amp;cp_id=11314&amp;cs_id=1131401&amp;p_id=12076) which could somehow be transmitted in real-time.  The software side of this is where I get iffy.  (Also, I am running a mac.)

Another solution could surely come from a document camera, but again the software leaves me dry.

To summarize:  I am looking for a hardware/mac-based software solution to live transmit document-based lectures over the internet.
This is a really really late answer (5 years late) but a natural solution seems to me to be to use OBS, open broadcast software. I believe it was developed for people who wanted to stream themselves playing video games. So it will certainly grab content from your computer and broadcast it. Personally I have only used it to record in the past. 

Note that I have no connection to OBS and it is free!
