I already have a zmq_reactor_pair function which returns an  
"anonymous" (UUID) inproc socket pair, that will work fine.

I can understand the local case (rebuilding ypipes etc. under the  
covers).  In the distant case if you tear down a connection, you have  
to have some way of guaranteeing that it can be rebuilt, not sure how  
you guarantee the kernel will make that magic happen.

But I have a workaround, and appreciate the quick reply.

Thanks,
