[zeromq-dev] question about zbeacon

Hi Benoit,

zbeacon does not impose any frame format; it allows the caller to
specify the format for beacons. Zyre does this according to the ZRE v2
spec at RFC 36.

So you could implement this in two layers as we do in C, one generic
UDP pub/sub beacon class, and then on top of that, the details of RFC
36. Or you could do that all in a single class. zbeacon has been
useful for other apps, which is why we made that a generic reusable
