[zeromq-dev] design for peer to peer messaging

Dear all,

I would like to build a service for electronics hobbyists to control 
their devices from anywhere. The targeted devices are primitive and 
probably cannot speak 0MQ. This project will host in a single VM, but I 
want to use 0MQ just in case I need to scale it up.

I have drawn a diagram to show my draft plan at:

In the beginning(single VM) it will only have one "Core" , one "MCU 
Frontend" and one "Web Frontend". The "Core" is responsible to route 
messages from User to MCU and vice versa. Both the User and MCU can 
initiate to send a message, and there is no need to guarantee a response.

In case I need to scale up, I can just many Core, Web Frontend or MCU 
Frontend as needed, with minimal configuration change.

Please let me know if there is significant flaw in my plan or a simpler 
way to do it.

Thanks and Regards,
Michael Fung
