A node ID is a string that uniquely identifies the node within a
network. Depending on the configuration used, node IDs can look like a
hostname, a hostname and a port, or a random string. AnyEvent::MP itself
doesn't interpret node IDs in any way except to uniquely identify a node.

=item binds - C<ip:port>

Nodes can only talk to each other by creating some kind of connection to
each other. To do this, nodes should listen on one or more local transport
endpoints - binds.

Currently, only standard C<ip:port> specifications can be used, which
specify TCP ports to listen on. So a bind is basically just a tcp socket
in listening mode that accepts connections from other nodes.

=item seed nodes

When a node starts, it knows nothing about the network it is in - it
needs to connect to at least one other node that is already in the
network. These other nodes are called "seed nodes".

    node ID - "[A-Za-z0-9_\-.:]*"
        A node ID is a string that uniquely identifies the node within a
        network. Depending on the configuration used, node IDs can look like
        a hostname, a hostname and a port, or a random string. AnyEvent::MP
        itself doesn't interpret node IDs in any way except to uniquely
        identify a node.

    binds - "ip:port"
        Nodes can only talk to each other by creating some kind of
        connection to each other. To do this, nodes should listen on one or
        more local transport endpoints - binds.

        Currently, only standard "ip:port" specifications can be used, which
        specify TCP ports to listen on. So a bind is basically just a tcp
        socket in listening mode that accepts connections from other nodes.

    seed nodes
        When a node starts, it knows nothing about the network it is in - it
        needs to connect to at least one other node that is already in the
        network. These other nodes are called "seed nodes".
