Both clients send a packet to a server, server sends the remote IP to both parties, both parties try to send traffic to either’s remote IP. Unless their nat firewall is evil, this should work.
That's no longer p2p, that's using a relay server like TURN

How so? With both users behind symmetrical NAT? TURN does not count as punching holes IMO.

Regardless, I'll claim that the real disagreement is more over how common symmetric NAT is: I claim it is very rare, and that the vast majority of NAT isn't symmetric... however, in another thread, the user you are responding to claims that "in [their] country" they've never seen WebRTC work at all. I'd wager that's a pretty local issue, with what probably amounts to a local oligopoly built with similar limitations, but if you live in that world it must be brutal. However, that's not WebRTC's problem: we should implement port mapping in clients and ISPs should, to put it as kindly as feels fair, "fix their shit".

WebRTC, in fact, merely passes e2e encrypted packets through the TURN server (which, by the way, is only required if both sides are behind symmetric NAT: the vast majority of NAT doesn't cause this problem, though you might need to do STUN).
> the vast majority of NAT doesn't cause this problem Hard disagree, I've yet to meet anyone in my country that has gotten any WebRTC service to work at all .

Can we have that do-it-all Opera back? RSS, email, torrents. Feels like we had it all internet wise in 2007-2010 and then decided to throw it all away.
We did not decide it. Google decided to kill it. In countries where Opera had major share Google ran aggressive and deceptive (something something faster) campaign with billboards, radio and tv ads. Chrome ads were also everywhere on their homepages (google.com, youtube.com). But more nefariously, Google kept blocking features and apps based on the UA agent alone. Add lots of tech demos with their custom extensions.
I got caught by this as a kid a few times, I was technical enough to know what was going on, and reliant on a screen reader (which Chrome didn't support back then), so it was definitely a memorable annoyance for me, but I guess quite a few people didn't care.

I think Vivaldi have both RSS and email, it's sort of the spiritual successor to the original Opera.... I miss the old Opera.
Vivaldi is roughly 1000 times slower. You need a pretty good computer to run that UI. It also lacks extremely basic features Opera had; like working LRU tab switching. I liked the idea, but it's impossible to recommend.

> During the brief period that open Airdrop / bluetooth file transfer was a thing, there was a short fad of spamming porn to nearby people on public transport. So that was the end of that. My recollection is that the end of that was Apple's worry about the protests in China, not any concern about spam on public transit. (The first Google hit: https://restofworld.org/2022/apple-airdrop-china-memes/ .)
Seems like such a simple fix though... Blur the shared photos unless you tap preview. Or unless it's coming from someone you have in your contacts. Or just not have it show the preview at all and obviously you would decline files from someone you aren't expecting to receive files from. Or the simple fix of just not having this P2P transfer option always enabled. It should be off until you toggle it on because you and…
I think it'd be great if Apple supported this, even if it meant an Apple AirDrop app for Android. Especially if it meant an Apple AirDrop app for Android.
The thing that usually annoys me about these services is they tend to give you an intractably complex URL to share with the recipient. This poses a problem because every time I need such a P2P transfer, I’m communicating with someone over the phone and they need the file on a computer (which may not even be their own, so email is also cumbersome). https://file.pizza does this better than most, as the URL consists of…
