People in the biological sciences are familiar with these sorts of 
restrictions. I'm not surprised by it either; it matters to me only when 
the restrictions compromise the information shared - i.e.,  if I believe 
that residence location matters for a cancer study, I need to publish 
enough information, or at least allow others _WHO SIGN THE SAME 
AGREEMENTS_ to get at the data.

The issue is not whether the data is truly public, but 'public enough' 
for real scientific validation.
