Hi,

I started recently using ZeroMQ (and CZMQ) and I have two questions -- any 
advice greatly appreciated.

1) I have a PUB/SUB pair -- what's the most efficient way to loop over the 
incoming messages
if we want to achieve maximum efficiency? Right now I have created an actor for 
the PUB end, 
an actor for the SUB, and a zpoller that polls the SUB socket in a loop, and 
receives one message
at a time. Is that (ie, using one blocking call to the zpoller instance per 
incoming message) the
correct way to do thing?

2) I've read about the STREAM socket type, to talk with non-0mq clients via 
TCP, and I was
wondering if there's anything similar for UDP? ie, let's say a non-0mq server 
sends out
data via multicast UDP, can I receive it somehow via a 0mq socket?

Thanks,
Andrew.
