So there is at least one extra device. NAT is a whole different beast, which can be defeated by ssh tunnels if you don't have network control.

Having said that, your key-lending analogy really sucks for this particular situation.They are in their right to deny traffic, but not based on the content of the packet.

This basically, means that the table rows don't mean anything on their own but you can learn the same stuff from D' as from D.
But there is always the utility-privacy trade off. When there is little data, you cannot randomize a lot before you start to lose information. On the other hand if the dataset is large, it becomes possible to make very strong privacy guarantees without throwing information away.
Randomization is the only way for micro-data to be shared. And as always, there is no free lunch in data mining. It's possible, research has been going since the late '70s on this topic. Companies are just not doing it.

The only role of the network hardware is to pass the packets containing the data from me, to my friend.
The problem statement is in my eyes extremely simple: send bits from one machine directly to another, the content is irrelevant, both parties consent. I claim that this impossible in almost all cases where you are a digitally illiterate person that resides in a posibbly restricted network. Because there are always third parties that control the network and their sole goal is to make your life miserable.
This is just a manifestation of the restriction of digital freedom, because isp/company IT dep. policies assume that almost all people are stupid: They buy IOT devices that are shit, don't have their pc security in order and download any .exe file there is to get. What is a solution? Put them in restricted networks, behind a NAT, with a draconic firewall. Make everything that the internet was designed to do impossible, without centralised control. My argument is that this is erring on the wrong side. Instead of disallowing anything that could be used for bad, they should allow everything that could be used for good. Mission critical systems should instead be air-gapped, or be part of a private intranet. As a rule of thumb: If you can get out, you should be able to get back in.

We've tried torrents of course. But the problem is that there needs to be a way for the DHT to be updated, or you need to run your own tracker.
This should be something that is easy, just like chat. but it turns out that it's not because almost everyone resides in a severely restricted network. Tbh i don't care what kind of data we send, it's meant to be an instantiation of setting up a pure p2p connection without using someone elses computer.

Me and my friend arrive at an arbitrary place, we have access to a network from there. Now, we want to share a file and the network connection is all we have. The challenge: make the file go from my device to my friends device in a pure p2p setting. If you know, for sure, that incoming connections are allowed this is very simple but here i want to explore which solutions exist that do not assume this.
Assumptions:
- Same network altough possibly different access points (one might be wired and the other wireless)
- We have no prior knowledge about the network, incoming traffic might be blocked (outgoing isn't for sure)
- No extra machines can aid in the transaction (no hole punching etc)
- Should work reliably for any kind of device that you have free -- as in freedom -- control over. that is PCs, android phones/tablets and macs. most of Apple's other hardware can be excluded because they don't allow for anything anyway.
- hard mode: We are both digitally illiterate
Goal:
- Send a file, p2p, from one party to another.
Me (MSc cs) and my friend (PhD cs) tried to do this last week. And it appears to be among the hardest problems in CS. I would like to discuss this and hear which solutions you might have for this problem.
Edits:
- this is not an assignment
- Added some specifics to the assumption set
- we're looking for practical solutions here.
- more specs

Wikipedia works well because there is no big entity behind it that might force their ideals onto the consumers. I always give when they ask for donations, starting from i was 16. I had next to nothing, but i gave 1 euro nonetheless. Ask yourself this: if wikipedia was a paid service, how much would you be willing to give monthly to keep it as it is? Just donate that much *12 per year. and be done. even if it's a euro, or 5, everything helps them.
Wikipedia is the last place we can go for information that --- as closely as possible -- resembles the truth and we can not afford losing it.

I currently run a stripped version of firefox called waterfox, It is very quick and supports the old addons, including unsigned ones.
If you run Waterfox + this stack of addons (over a VPN, with a pihole dns set up ofc)
- Decentraleyes (decentralises dependecies)
- HTTPS everywhere (Forces HTTPS if it's available)
- NoScript (blocks JS by default)
- Privacy Badger (blocks trackers)
- self-destructing cookies (automatically delete cookies)
- uBlock Origin (blocks ads)
- Random Agent Spoofer (Spoofs referers, ip, resolutions, against browser fingerprinting because you are very unique when you use the above)
you are as protected as you can be without going completely TOR.
edit: wrote origin after uBlock
