Are you looking for the broker to identify a total ordering over all
messages going through an exchange? Do you need an incrementing
integer?

The feature on the c++ broker was for a totally ordered sequence of all messages through the exchange. The pre-1.0 AMQP model is not ideal for pub-sub where you want all subscribers to receive events in the same order. That extension to the exchange was a way of working around it where absolutely needed.

I think actually a modified browsable queue would be a better approach, where messages were deleted after being seen by all browsers.
