[erlang-questions] conditional pub-sub in gproc

[Loïc Hoguin]

Sorry I should have been clearer.

I'm using global gproc to locate processes that may be on any node of 
the cluster. But sometimes I run into gen_leader's issues (for example 
if a node crashes) so I was wondering if I could manage still using 
gproc for my purposes without gen_leader.

Currently it's easy to broadcast information to other local gprocs but 
not so much to retrieve remote data, similar to what get_value/2 or 
where/1 would do in a distributed context.

It would be nice to be able to have a cluster of local gprocs and easily 
access them from any remote node, similar to how bcast works for 
broadcasting.
