I travel to events and would like my team to be able to share files and chat over a local wifi network (or ethernet) without internet. I would have a router and APs.
For example: at a convention my graphics team share a lot of files and unfortunately 90% of the time we have to use thumb drives or portable HDDs to transfer files. It sucks.
Would like it to be a more advanced and further reaching AirDrop, if that makes sense.
I found this topic, but not sure if this is a feature or just a feature request:
