I thought before of doing something like this but did not manage to seat and do it. The one that I imagine is a simple web server on a rooted android where we can create a hotspot and change the dns to serve something like a.com locally (the reason to have [hostname].com is to make easy for people around to connect and load the offline webapp) then people connect to it and can see postings from others and post too, because it's a offline capable webapp everyone will have all data even after disconnected. That is a thing that I miss when going to meetups to easy share info with others locally.
