I've suggested a routing protocol to the lemmy devs - to use federated instances to route all the messages to other federated instances. The idea was received with some interest, but it seems that people believe that there's still a ton of performance that can be squeezed out from the current architecture through optimisations.
I usually just VPN to my routers if possible. Point to point is feels more reliable than a hole-punching mesh or proxy. On the other hand, this seems to create an end-to-end secure tunnel.
Good thing that what they are building is super transparent, open source and distributed. That critical post wasn’t even deleted.
As long as that remains the case, I’m happy that Lemmy is a place where you can find all kinds of views represented.
