Yeah, good point. Personally, I'm torn on whether I would ever want to give up my whole-network firewall, especially when there's a wireless network in the mix

Yeah, good point. Personally, I'm torn on whether I would ever want to give up my whole-network firewall, especially when there's a wireless network in the mix. My servers' ssh logs are choke full of brute force attempts. I would hate to waste my wireless bandwidth and battery life on such attack attempts. On the other hand, IPv6 address space will be so sparse that maybe such attacks won't be practical...
