Re: [paho-dev] Contribution of MQTT Servers (Mosquitto and RSMB)

Hi Ian,

I agree that option 1) makes the most sense. We might as well start
out on the right foot.

I'll look into getting the proposal into HTML and a presentation done
in the meantime. If there's anything you'd like to contribute to the
latter I'd be grateful.
