[change] neal lesh on phone-based tools for community health workers

i think most people on this list know (or know of) neal. he's an all around great guy and a big reason why we've been successful at much of the health work we do in uw-cse. neal gave a good talk on his work at the ict4d seminar at penn. you can find the video at http://www.youtube.com/watch?v=WJeVwc6bK_k. if you haven't seen neal speak, it'll be well worth your time. you can find more videos from the penn seminar at http://www.youtube.com/user/ICT4DatPenn.
