i hope 3com knows what they're doing... An incredibly extensive firmware line will have to be released for these cards. Personally, i doubt i would benefit from this technology as i have a router. Im sure there will be problems if both the router and the nic have a firewall. Lastly, this will be a software firewall (if im not mistaken from what i read) and there is no question that i'd choose a hardware firewall over a software one. The idea is good, but they probably need to strengthen the security in the operating system rather than in the nic. The price of some of the equipment is also a little steep for those who are looking to use it in a home network rather than in a corporation.
