Thanks so far ... well, in my application I want to be able to perform some tasks as soon as a Mac is connected to the local network. That is why I want to monitor the local network. Installing an additional app and making holes into the firewall is not what I want to do ... so I think I will use the MBS plugins to listen to some common services such as file sharing, ichat ... and hope that it's my best bet.
But as Tom already wrote: If there are no services running, I'll have no chance to discover the Mac.
