With a cardsharing client you don't need to spoof anything though. You have one "legitimate" reciever that runs the cardsharing server which decrypts the ECMs, and the rest aren't visible on the network as they don't talk back.
Satellite isn't unicast, which is a directed signal from one point to another, it's broadcast. Cable is STILL broadcast, despite the physical network and even under a full IPTV system will still be broadcast as the cable coming into your home is part of a shared branch in a tree network. That means that there will always be something on the wire that an STB can gain access to, even if it's just the same channels your neighbours are watching after a switch to SDV.

Ah but now that Nagra3 is available on the VM network, it gives more motive, means and opportunity to those who wish to try cracking it!

Not really, the UK market is relatively small compared to the European one which already uses N3. It doesn't even need to be cracked, as long as they cardsharing works then they're not going to care if it's cracked or not. Infact, people will be happy it's not because if it's cracked they profit from the upfront STB cost only, with cardsharing they can charge recurring subscriptions for access to the cardsharing server, so there's potentially more money to be made from it.
