[CQ-Contest] Cluster network update - was: Reverse Beacon Network- too much success?

While everything you say may be true, it has absolutely no impact on securing the system from anonymous abuse.

As simple as it is for DNS to be controlled by root servers and replicated worldwide, a database of authorized users could as easily be implemented and replicated to all node, leaving the connectivity architecture intact.

Organizations such as ARRL DARC and other volunteers could easily take on the task of verifying amateurs for access.

Once completed, it will be a simple task to identify abusers.

It seems to me, the only people who would desire the system to remain open to anonymous abuse would be those wishing to abuse the system or support those that already do abuse it.

You won't ever sell me on a position that it can't be done or it's too hard or to challenging.

A central server system has been discussed in the past, but has always been rejected as being a single point of failure, removing local control, relying on someone to provide the service for a long period, etc.  While things like sms, twitter, aol-im, msn-im, irc, aprs, and other services may seem like a nice way to do it I would worry about the long term viability and our use being disrupted by business decisions or changes in other services for security or other reasons.  When ar-cluster came out there was a move to organize into regional sub-nets which would connect via one hub... that fairly quickly fell apart when everyone realized that a single failure could split the world into a bunch of disconnected islands.  The software was modified to allow more redundant connections and automatic failovers.  This is similar to how other cluster software works now, most nodes have many redundant connections so a single failure affects only the local node.
