Data access/usability vs. security/privacy is a worthy concern for building data. I think we will see a designation made based on level of detail. Blueprints (with details about structural features) should not be publicly available. However, simplified floor plans for public spaces are already publicly displayed, as required for fire evacuation purposes.

Where that "level of detail" line is drawn is an important discussion as the availability of indoor maps from Google, Bing, OSM, Micello, etc. continues to expand.
