Re: Individual Members of PeerGroup

Paul,

Creating an OutputPipe object with the desired set of peers should 
provide the functionality you seek. Using rendezvous propagation may 
work given the correct service name and param, however, we advise 
against it, mainly due to the potential flood everywhere, and as a 
result it has become more restrictive in the upcoming release 2.3.5.

Is this a static set of peers, or you looking for suggestions on how to 
dynamically create one?

if it is the latter, perhaps a ping message over the propagate pipe 
results into a unicast response over the same propagate pipe.
