What I’d like to do use my computer I have at home. It is online 24/7 on broadband. I could link my account(s) so that those servers can store data on it and when I use clients I can largely use my own computer as a server. I could even offer to host 10 or more guests with rate limiting. Many others could do the same to reduce the load.
Servers would queue up the work and handle it under their constraints. With my account I could even list my home server so it could get pushes directly and offer that data to the server(s) I use. It would ensure I get posts quickly and offload the load on servers. @paul
