I have a vodpod widget on my blog and it's excellent! I think you'll love it! Bloggers, this is a great tool! They have a free and pro account and I'm asking them if they have discounts for educators. No response yet,but if I hear something back, I'll let you k now! In the meantime, give it a look. I think you'll like it and the potential you'll see in it for your classroom or presentation.
