It does this by IP hopping: 'The Invicta system uses special cards to link protected computers to a central control unit. It lets clients decide how often they wish to vary IP addresses and specify which applications may be accessed on their network.'" I've always wondered if there could be a way through software to do this. Of course, a centralized server would need to route which would be a major bandwidth bottleneck.
