Localized Nostr for communication at a local event would be really neat. Something you have access to when you connect to the LAN and you can see everyone else's notes at the event. 

 Might that not increase privacy/ security holes?
Imagine how this might go at a bitcoin/nostr conference  

 You don’t have to turn it on 

 Yeah I get that would be an option.
 

 It could. That's a problem for whoever actually tries it. 

 True. I guess not for me but others will find it good
