When a job is launched from a xbook, that job can return information/meta-data files to the xbook. For example, currently the athena notebook, stores summary graphs into the xbook folder. Therefore, the xbook manager should be able to serve files. One way to do this is have the xbook manager implement a HTML server port that can serve files. Then xbooks can then store URLs to these files and so they are easily retrievable when a user is viewing the xbook. Alek is currently working on creating a HTML server port.
