I think the true future of anatomy atlases is to address the kinds of applications you're describing. Open source anatomy atlases can become toolboxes of visual anatomical knowledge. Subsets of atlases can be used for patient education, with structures labeled and styled to meet the needs of the audience. Atlases can also be used as visual indexes into collections of medical data.

Finally, we need atlases that represent the breadth of humanity. It's far too easy to view the "typical anatomy" represented in a major atlas as "normal anatomy" with any variations being abnormal, rather than just less common. Open source atlases can fix all of those problems, ultimately providing a comprehensive and collaborative view of what human anatomy really is.
