Great idea to use during live events. This year, during the TESOL conference, I blogged live by using the iPhone and writing on a post as I watched the presentation. Some friends said that the profited from it as they couldn't be there and I was sharing at the exact moment things were happening. Would love to hear from you if you try it any time soon.
This idea was presented by Claire Sisbkin during the TESOL Conference, and it's just really, really neat! It's a dictionary students can listen to and see the pictures in their ipods and iphones.
