Introducing Miranda: the Cluster

In preparation for a talk I'm giving at DOSUG I'm going to post my thoughts as they develop.

The Cluster is the collection of all the Miranda nodes that the local system knows about.

It acts as a repeater: when the system wants to tell the other nodes about something, like a new user or a new topic, then a message is sent to the Cluster.

Elections, where ownership of the systems subscriptions is decided, is done by the Cluster.

When a new node connects to the system, the Cluster is notified.
