This is essentially what I was attempting with http://beginner.org, and we were using Screenhero. The biggest issue I encountered was on the scheduling side; it's difficult to coordinate dates/times and availability between two people with potentially different levels of commitment. If you can figure out a way to reach a critical mass of available mentors across each of these languages and frameworks so that you can truly offer "instant" mentoring on demand, this will be sweet. Incidentally, we're shifting to a self-teaching model because we couldn't overcome the scheduling challenges.
