Reviving the Firewall Design Program?

rcha101 asks: "I'm not sure if many of you are aware but Robert L. Ziegler use to host (IMHO) the best online firewall configuration tool (formerly available here here, check out the link now for his sad synopsis) until recently when he decided to pull the plug on it. I have since been trying to contact him in an effort to get this tool back online and develop the IPFW2 side of it (correct some of the rules, add extra features to it etc) but have had no luck. Does anyone know how to contact him? Has anyone else been in a similar situation? What web tools do you use that could suddenly disappear overnight? Robert are you out there?"
