Comments
Sorry for the delay in responding, I'm completely swamped at work at the moment and that has an impact on the free time I have for mosquitto. I think this sounds like an interesting idea and initially positive about it - but haven't had chance to think about the implications yet. |

In order to solve this problem, I would like to discuss the possibility of introducing the following functionality to the mosquitto bridge:
