Many people have thought this too. A sort of p2p social network? You solve a handful of problems but create many new ones to overcome. For example, using Facebook on multiple computers is simple right now. Now lets consider a p2p model. How do you handle uploading photos from a computer that isn't your main/home one? You'll need to basically synchronize content between the computer involved and your main one. There's also the case where I want to share a photo and not store it locally at all. What happens when some of the computers involved in your friend network are turned off and those friends want to view photos? I'm not sure you can make it completely P2P. You might need a central 'cache' of new content which then just gets pushed down to your friends once they sign in. And since everyone is disconnected that sounds like everyone needs to have a copy of their friend's data. I'm not interested in storing their photos on my PC. Just some random thoughts that came to mind.
