volunteering assistance, and maintains no further state relative to
the request.
The Server determines its ability to assist by checking for the
presence of the necessary information, either in the request or in its
own Dump/Load Data Base. If it can assist, and the request was not

a single transmission of an
assistance volunteer message. It maintains no state to recall that
any of this has been done, as it may not be selected
by the target to
be the assistant.
