Scott great post and ideas...but sadly this whole technique demoesqueish sharing scenario is a smoke screen to a previous Bombarded request for demos which in reality to share "How You Do it" falls into the same category.....Yes we would love this to all work, Yes learning from each other in a perfect world seems feasible,but its still a VERY PERSONAL thing in How we all play .... Yes with all the Video opportunities such as You Tube, Skype, Camfrog we can have a great learning experience between players in that we can all learn from each others way of doing it, Yes scott it all makes sense on paper or in theory....BUT will it happen....not likely.
Although in a smaller get together maybe 1 or 2 people in a P2P type of session on one of the programs mentioned above it could be super beneficial....I would suggest that you Video tape your technique lesson & then you can share with with whom ever you like online.....or although more difficult set up a time to do a group lesson online via camfrog/skype etc etc ...try a technique a week and see what happens......
a video is worth a thousand words.
