I don't know why, but I had a visceral reaction to the browser prompt to install the extension in the paddleover demo. This is despite the fact that I'm a developer, and I'm well familiar with bittorrent. Maybe it has something to do with the fact that I feel like I have to be keenly aware of what my BT client is doing at any given moment. The thought of letting a BT client run unchecked in my browser is disconcerting ... am I completely off base here?
