Is this the real Public Health Use Case?

The HealthGrid conference has been very good for me to stew on a number of important questions spawned from my favorite: "so what?"

What struck me more than anything in listening to the various folks from the clinical, research, bioinformatics worlds (the primary attendees of this conference) is that the real problem they are trying to solve is to get access to data from trustworthy sources so that each can do their job. So, in the world of public health, would it follow that the use case that matters most can be generalized as "Data Access".

If we solve that -- and then use the public health programs (biosurveillance, reportable disease surveillance) as the jargon to describe that -- do we solve 80% of the problem?
