Returns true if the component wants to be notified of after packets were
processed. Processed has different meaning depending if the packet is incoming
or outgoing. An incoming packet that was processed means that the server
routed the packet to the recipient and nothing else should be done with the packet.
However, an outgoing packet that was processed means that the packet was already
sent to the target entity. 

@return true if interested in incoming traffic. false means outgoing.
