A more complex example might be for a teacher working with a group of students:

• student-{name} bag for each students work
• teacher-course bag for the coursework, editable by the teacher
• teacher-tools bag for custom tools used by the teacher

Those bags would be exposed through the following hosted wikis:

• student-{name} hosted wiki for each students work, including the coursework material
• teacher-course hosted wiki for the coursework, editable by the teacher
• teacher hosted wiki for the teacher, bringing together all the bags, giving them an overview of all the students work
