bear in mind that I am far from intimate with some of the engineering

Before proceeding I would strongly recommend you dig into the existing
HTTP server and client example. There may be duplication between
those and what you propose. Indeed, if you could evaluate what we
have done and propose or write improvements, that could be very

Yes, the release process for clients lags that for the broker at the
moment, partly because the whole team is very busy, and partly because
we are adding new features to the broker which, as Matthias says, are

Yes, I think there may well be similarities. Take a look at the code.
Maybe Tony will be tempted to comment over the weekend but please
