* The active object list is scanned for each client once in a while,

and it finds out what objects have been added that are not known
|

|
by the client yet. This scan is initiated by the server and the
|
||
|
|
result ends up directly to the server.
|
||
|
|
* A network packet is created with the info and sent to the client.
