Many, many of my college courses were online. Online degrees, etc. are becoming more of the norm. At my alma mater The University of Toledo we have undergraduate and graduate degree programs obtained through nothing but online courses. QASP is coming in with CENTRAFLIX at a great time.
Image being able to anywhere in the world teach using online courses. 3rd world countries as they modernize are going to be up on the latest and fastest wireless internet. No need to bother running ground based cable etc. I do not know how well Centalix does or will do in the online education boom coming but market going to grow over years to be very big and common way to learn. To get an education. Sure cuts down cost of needing buildings and admin staff etc. Teachers can teach remotely on line from home. Be cheaper to give every kid a computer, the software and on line access then build schools in these countries.
