I never really pursued those options further because I'm somewhat opposed to having a central broker (for lack of a better word) that acts as a single point of failure, and adds complexity for routing messages to and from the pieces of my distributed system. In the last distributed system I helped build, we didn't feel good about having a central point of control (and failure), but in the end we decided that a fully distributed system would add unjustifiable complexity and expense. Fully distributed systems seem to grow behaviors that are as hard to fix as human communication problems. I have no idea whether that experience applies to your project, of course.

Fully distributed systems seem to grow behaviors that are as hard to fix as human communication problems. Yeah, my favorite example of a fully distributed system that seemed to grow behaviors that are as hard to fix as human communication problems was Amazon messaging system that carried *gossip*. How human like is that? At 9:41am PDT, we determined that servers within Amazon S3 were having problems communicating with each other. As background information, Amazon S3 uses a gossip protocol to quickly spread server state information throughout the system. This allows Amazon S3 to quickly route around failed or unreachable servers, among other things. When one server connects to another as part of processing a customer's request, it starts by gossiping about the system state. Only after gossip is completed will the server send along the information related to the customer request. On Sunday, we saw a large number of servers that were spending almost all of their time gossiping and a disproportionate amount of servers that had failed while gossiping. With a large number of servers gossiping and failing while gossiping, Amazon S3 wasn't able to successfully process many customer requests. http://status.aws.amazon.com/s3-20080720.html Also watch out for backbiting, speaking ill of others, spite and slander.

RE: What is The Hive?
The Hive is a group of companies under The Hive umbrella. Mostly LAMP Engineers. Their main source of revenue is singles.net a dating service. You see it all the time on Yahoo web page. They are virtual company and each developer works from their house. Pretty cool company but they are VERY PICKY on who they hire.

Is that to be expected with the filtering I just put into place or is that an indication that something is not right? Sounds to me like IPv6 followed by IPv4 fallback.

In your last copy of the script, you left out the return traffic. /sbin/iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT You seemed to replace it with the loopback traffic rule.
