It is definitely a great initiative, and Khan academy has always nailed course materials. I can't wait to see what they've done with this! It'll have its share of pros and cons, it'll work for some, might not work for many. This will work out for most if its part-time and they go to in-person as well, to get both social and explorative schooling. For self-learners this will be a gold-mine, for anyone who wants to take the cognitive and explorative approach will probably benefit from this.
