I've gotten a couple of emails on this, so I decided to add a link to the main site page and a special page summarizing the solutions you've provided here:

Feedback would be appreciated. Also, I'd love to be able to add screenshots, but I don't use any of the affected firewalls. So, if you're feeling altruistic, post them here or email them to me and I'll add them.
