I think the problem is that both Sugar instances are using the same
gconf instance that is initiated by GNOME. In the past we have used
GConf-dbus so that there's a gconf instance in each Sugar instance and
the settings are saved in each ~/.sugar/default/<profile>, but I do'nt
know if this may have gotten broken at some point. Maybe Sascha knows
more?

Can you check that avahi-daemon is running and that your firewall
isn't blocking the ports?

Thanks,
