This reminds me of the CES app, which many attendees also found very useful.
Before long, given enough intelligence and knowledge of the user, our digital assistants will indeed be able to recommend a schedule of conference papers to us, or CES exhibits to visit, etc.
Cool app; now for iPhone4s users we just need Apple's AI voice recognition Siri to tell us which are the most relevant papers for our purposes and we are all set to navigate the conferences at the cites, or even remotely through interactive sites. With OS5 promising Siri to be "deeply integrated" into the operating system who knows what answers we might expect from our digital companions. Very cool indeed!
