It is my understanding that medisnap was designed for use in a single
practice. Furthermore it might have legal implications to provide what you
ask.
So I guess medisnap could be enhanced to provide this but I would recommend to
do this at another level. Practice A must not know that practice B has seen
patient XYZ unless there is consent of the patient. In that case practice A
might flag the record accessible for practice B
Both might then share the same image files or annotations but I believe this
has to be added to medisnap.
