/* Social Pane
**
** This outline pane provides social network functions
** Using for example the FOAF ontology.
** Goal: A *distributed* version of facebook, advogato, etc etc
** - Similarly easy user interface, but data storage distributed
** - Read and write both user-private (address book) and public data clearly
** -- todo: use common code to get username and load profile and set 'me'
