<para>whether a particular participant ID should be kept unique,
with any new (automatically keyed)
connection using an ID from a different IP address
deemed to replace all old ones using that ID.
Acceptable values are <emphasis remap='B'>yes</emphasis>
(the default)
and
<emphasis remap='B'>no</emphasis>.
Participant IDs normally <emphasis remap='I'>are</emphasis> unique,
so a new (automatically-keyed) connection using the same ID is
almost invariably intended to replace an old one.</para>
