Re: The real crime
Of course it is obvious. This had been done by more than one communication product that communicated via text or voice rather than video - VOIP phones in a VOIP to VOIP call for instance. The only difference between that older technology and what Apple was doing with Facetime was that Facetime was passing video instead of text/voice, and the endpoints were smartphones instead of PCs/desk phones.
I mean, are you seriously going to argue that if you were designing a video conferencing system where two people could see/talk to each other on their smartphones, that your first instinct wouldn't be "have phone A send IP packets directly to phone B, and vice versa". That such an innovation is worthy of a patent? If you do believe that, are you currently a patent attorney or patent examiner?
