Using zeromq in a distributed load pipeline, can I get the address of the last server a message was sent to?

It think you'll want to use the X(REP|REQ) sockets somewhere in the topology for this. You might want to checkout the monitered queue device: http://github.com/zeromq/pyzmq/blob/master/zmq/devices.pyx.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
