With push/pull there's no reply, so no way to tell the sender the
message was (or was not) received.  You could do that using another
socket back to the sender but xreq/xrep seem more natural since xrep
already routes replies to the original client, across devices.

Don't know, sorry.  I'd assume there are ways of making this work
using a queue device but it's not something I've done yet.
