[zeromq-dev] Question about Strange Socket Pairing

[Matt Goodman]

Mmkay.  That is what I was feeling.  So a followup question would then be
what it the correct way to go about this?  The push/pull socket thing works
well, I am just concerned about the HWM semantics of blocking.

I would much rather use a Pub/Sub connection model, but I would need
multiple publishers with a single subscriber?  This seems a bit backward.
 I think the XPub/XSub model has what I need, but I am unclear on the
semantics of which calls bind and which connects . . .
