An Article about "Comparison of Firewalls"

Hi all hackers ! Yesterday I googled for "Comparison of Firewalls" and found nothing. I was very upset about it, so decided to create one article, and put in Wikipedia. But since, I am only 1 man, I don't know everything about firewalls. The article's target is to compare features of all Firewalls, both Home and Enterprise must be put to test. I would like productive discussion about it, what you like and what dislike, and please add data about some firewalls you know... like ZoneAlarm, BlackIce, whatever you know... The article is here: http://en.wikipedia.org/wiki/Comparison_of_Firewalls -any feedback ? -Fenix*NBK* 2.10.2006.
