I use for a project an Arduino Yun with Node.JS+socket.io to provide interactivity between a smartphone, driving through a webpage different devices. I would like to enable this service for several smartphones at the same time. However I would like to work in the very same conditions that a (well configured) hotspot does:

1. I want to ensure that no user can see the other users on the network,
2. I want to have a limited number of connections on the Yun at the same time,
3. I want to force the different users when connected to the wifi to be routed to a captive portal on the first connection.

Does anyone know first if it is possible with an Arduino Yun (maybe some actions must be performed on a NodeJS virtual server as point 2)). If yes, do you have a tutorial or any clues (do I have to use LuCi).

Last question, in the same topic, I would like to use a fast granted access using NFC tag emulation to provide wifi credential. Does anyone try this with Arduino Yun and a shield?

Thanks
