True there will always be students goofing off in class- I was one of those up until a month ago. At UNC Chapel Hill, this upcomming year is the first year that every undergraduate in the school with have a laptop, and 50% of the student will have integrated wireless. The idea of backchanneling hasn't caught on yet though, mainly because ultimately, there are other methods with which to contact the instructor and instructors at UNC are not are forward thinking as many would think they are, at an infamously liberal institution. It takes an environment with ample power supplies and access to power plugs, wireless access signs, open professors, and technihcally educated students to get backchanneling. This is of course much easier when you have as smaller school, and maybe if the IT departments at some major universities would jump on this idea and start educating the student populace, it can turn into informative chat instead of drool checking and hot chick spying chat.
