The pathologist in the lab and the nurse on the floor and the doctor visiting with family all may use the images simultaneously. The single copy of static quality X-ray film need not be walked over the miles of hospital corridor. However, two immediate problems are obvious. As a consequence, confidential medical images might be called up and viewed anywhere in the world.

Often, the law has problems with new technology since new actors begin to act in ways that the law prohibited for prior actors.

Typically, technological evolution starts in a confined space affecting not much more than the expert innovator. Also within that confined space, experts come to expect unimpeded access to the technology.
