in the case of connecting to multiple jabber servers, the user should
be able to tell which XO in the neighbout view belongs to the same
school
<br>2. get the geopraphical location of another user<br><br>In future
versions of the neighbor view, or through other activities, the user
should be able to filter for specific XOs according to location, or
school(in the case he's connected to many servers). Two children in the
same school should be able to recognize each other even if they are
connected through a jabber server, other then the one in the school.
<br><br>It can also be useful for locating an XO in case of theft.<br><br>I have also added a ticket(4405) for adding the public id in the buddy list properties.<br><br>It is a small part of data(both IPs, private and public), which can be harmfully incorporated in the telepathy services.
