Thank you very much for asking of me and caring to be of understanding of me. :) That is indeed correct, I am DeafBlind meaning as you guessed significant lack of vision as well as hearing. My biggest concerns are actually being able to be involved in finding people and possibly comes something of it. Which is why up until I created my deafblindminetestgaming.com site. I been having issues with this because I lost my most involved forum I was in to supar staffing of helping me with two concerning reports. As well as Discord giving me such pains with my account because it's being "comprised" regardless of the passwords I use. So I had to stop using it as their 2FA is a piece of trash ONLY allowing smartphones. Which doesn't works for me. :(
So yea a LOT had happened the first half of the year and still trying to "get back up to speed" to this very day.
This isn't news, there plenty of networks that already does this. You might be just a command away in fact to get a "Player Server" or "Player World" in fact.
Also I hate to break it up to you but that isn't federation, that more like "we provides the connectivity and you do the rest". Not that much different than saying using your own web server with a CDN network.
