Another question: was anyone in attendance asked to sign an NDA before seeing the presentations of companies still in stealth-mode? Most bloggers aren't talking about the ones that haven't released and I was wondering if they're just being ethical or if they were prohibited from doing so.
I doubt it - they don't record much else that goes on there, so that people can be candid. Makes sense, because the whole thing is put on for the benefit of the people there, be they buyers or sellers.
