On some hotspots, UDP broadcast and/or multicast is blocked. On other hotspots, client to client access is blocked, even if you know the IP address. One test case is bulk connecting, i.e. issue zmq_connect () to every other IP address on the block. That fails on perhaps 20-50% of hotspots, even in offices. It's a bit of a mess. Since we're not in control of the hardware we cannot be very ambitious. Hence my preference for the smartphone hotspot. -Pieter _______________________________________________ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev
