The proposal I put forward is far simpler than the kind of engineering that goes into making Facebook work. You're confusing novelty with complexity. There's nothing complex about taking some data, encrypting it, and sending it to another computer. P2P/F2F public-key cryptography networks have been around for about a decade (see Justin Frankel's WASTE http://waste.sourceforge.net/ http://waste.sourceforge.net/). Putting this together with some advancements into an unhosted browser app is not a huge leap. The problem isn't going to be the technical complexity, it is going to be the UI and slow upload speeds. The business model for this kind of network is going to be the same as the business model for BitTorrent - advertising on public directory web sites.
