Thank you for the very detailed explanation. I figured for services using a different protocal would be easyer as they can be handled almost independantly.

Would i need to modify the code of every services to man in the middle myself surly since i control the private key i can just do it after it leaves the service then if i pipe that back to my "universal" incoming it would distribute it to the relevent services?

I dont understand why the last approach breaks mastadon-lemmy interaction? It seems like the best solution if it wasnt for that.
