I'm not sure how important security is in a z-wave lightswitch because any vulnerabilities for your network would be in the zigbee-to-lan gateway. The devices are rather dumb themselves, just an address and a little bit of state. If someone did compromise the lightswitch, it would still need the gateway to do malice. If you're talking about a full processing node, that would be a real concern, like some of these wifi products that can sit on your network, sniff traffic, and compromise you via egress. I have a real concern over all these unknowns.
