Are you saying that when a particular service record is created in the
SA, an event is generated to a set of interested endnodes ? I don't
think there is a way to do that. The only choice is for the endnode
to continue to poll the service records based on the matching criteria
which we would need to define (ServiceID or name perhaps).

I don't think there is a way to tell a node is the last (full) member of
the group. Anyhow, if this were done, how would that node know to rejoin
once another node came along ?
