The only point I would add to the equation is the important of thinking outside the box and outside your country. P2P also means being able to see slices of life from around the globe – how else would I see some Israeli, Korean, Thai, Spanish, (etc) movie. It’s a wonderful opportunity for peoples from all over the world to share resources, and culture in real time. Nothing makes me happier than to look at the flags indicating the tens of countries all participating in communal cultural sharing.

In my book it should really be PHP – people helping people.
