25 MB wasn't even enough to send a single full res screenshot of my desktop.
Its 2024 and we still lack the basic functionality of file sharing between peers without a corp dictator restricting and snooping.
Not that the functionality does not exist (p2p, literally) but if my grandma cant receive the family pictures its not basic.
EDIT: it is possible i am remembering this from when it was 8MB.
Empty desktop is just a few kb but it was not that hard to open enough stuff to exceed 10MB
Til that i have been sending screenshots of only half my screen for not reason
The issue is the absence of being able to port forward in a lot of places. UPNP exists on some networks but it's usually disabled. But if we want actual peer to peer we're going to need to implement some way to accept incoming connections EVERYWHERE.
Once an end-to-end, encrypted, connection is established between a pair of peers then anything can be sent through it. The establishment proces is generally facilitated by a server of some description so neither peer needs to allow inbound connections. (I'm a long, long way from being an expert on this and happy to be corrected - but this seems like network fundamentals?)
this is true, but the problem is that it's really complicated, and not always reliable. Mostly due to NATing within the networks. Firewalls don't help but you can get around those easily enough.
There's no guarantee that you'll get a reliable P2P network connection over a NAT unless one peer isn't NATed. Which is unlikely.
TL;DR we would probably ddos the internet very quickly if we tried at the scale of something like discord.
