Just googled it. Skype was initially p2p
So, nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6 is inventing the Skype of 2008 😂😂
Discussion
Skype never quite worked well though
It's very important to reach that point where it just works, so it keeps just working
Maybe the #nostr protocol will make p2p more doable
