[zeromq-dev] 0MQ protocol stack

[Paul Colomiets]

Hi Martin,

We can introduce notion of out-of-band messages. This should be a flag on messages which are for other means look like normal. They can be used for connection initiation and heartbeating. (May be also subcriptions, but I don't sure). This way some options sent at initiation could probably be updated later.

Posix has OOB data. And notes: "The significance and semantics of out-of-band data are protocol-specific". I didn't see any actual usage of
OOB anywhere, but probably it could be used for zeromq.
