This feels like something Apple should do with iPhones. Find My and air tags was already a huge success because of the ubiquitous nature of iPhones. Apple could add this to iPhone, sell it as privacy focussed. Let you message anyone in your iMessage contacts with a new bubble colour. Propagate over Bluetooth when you don't have internet. I can see a snazzy Apple reveal for this showcasing it's use on a cruise ship, i…

The US, and likely Chinese, government(s) have too much potential leverage over Apple. I wouldn't trust that Apple would do this securely, or that the government would allow them to release it.

Apple just gonna disable it for China like any other privacy feature.

Could someone please explain in what situation do you use a BlueTooth messaging app? Like, even BT5 range won't exceed 400 meters. What good is this? You're not going to send images to journalists from protests with it (you'd do wisely to keep it in airplane mode until you get home and then you'd upload them to their securedrop or whatever), and you don't need off-band security to let the kids know it's dinner time.

I've wanted something like this numerous times for long flights.

I also have recently got into caving, which usually results in 5-50 people camping over weekends in rural Kentucky. No signal most of the time.

Earlier quoted context omitted.

Unfortunately iPhones aren't ubiquitous outside their home market. It would have to be on Android to be really useful in the places this would be really useful , i.e. places where regimes turn off the internet when things go badly for them (current situation in the US notwithstanding). That's not to say iPhones shouldn't have it, I'm all for that.

Home market for iPhones is the whole world.

In India IOS has 4% of the market share of mobile devices whereas Android has 96%.

It's criminal that cell phones are bristling with incredibly advanced radio technology and yet they are by law not allowed to communicate directly with each other over a distance of more than a couple hundred meters without assistance from a licensed and centrally controlled base station. Meanwhile a $10 walkie talkie using primitive stone-age radio technology can go many miles with zero infrastructure, but by law is not allowed to be used for data transmission. This is a choice our governments have made, not something inherent to the technology.

I sometimes wonder if we couldn't have completely different public internet topologies if

a) Wireless local networking was invented and popularized earlier b) We had transitioned earlier to IPV6 or some other protocol with an address space as huge, thus making NAT not as pervasive as it became. b) We didn't have hordes of VCs financing walled gardens and social networks.

This would've been useful during the Iran shutdowns last week. Bluetooth mesh is one of the few things that keeps working when carriers go dark.

The regime in Iran has so much to hide it's unlikely that they will enable unsupervised international communication ever again. Other countries don't seem ready to do anything about it.

There are a lot of old and new mobile applications doing this. If there is anyone doing some research in this space, maybe take a look at our "DisruptaBLE" implementation for delay tolerant networking on embedded devices: https://openreview.net/forum?id=xy3Y6cLOV2
