You could find entertaining to know that this gadget is using the shindig server http://pruebasitioweb.ibercivis.es/ibercivis/monitorizacion/mapas.html
actually, their person and activities services, hanging at the end of the java thing, are fetching data from a BOINC database, and they will fetch realtime data when in production. In the further far future, we should switch to the php thing, because it is the language BOINC webservers are using nowadays. But we have other reasons to train people in Java, so following on Cassie shoulders was a good options. Each activity is a line between the user and our servers. Now that the access to Person data has been fixed, each activity is/will be able to read the real coordinates of the person involved. The advantage is that the same map can be used to show activities from the whole network (friends of the user 0), from a team (now friends of a team/user ID, in the future 0.8 the idSpec will be useful here) and from the friends of the owner, of course.
