What's most fascinating about Niklas is his recurring theme of P2P on Kazaa, Skype and Joost. At the first sight it seems that these companies are disconnected (different markets) but his true accomplishment was to leverage the P2P technology for different use cases (file sharing, voice and video) and at the same time making it transparent from the user experience. I also find fascinating that even Skype's business model seems to be P2P-driven: Skype seems to charge only for services that use the company's infrastructure, while P2P services (those that do not directly use Skype's servers) are free.
