Is there a way to set it up so user@example.com can be a lemmy account and also a mastadon account? I seen people using subdomains like user@lemmy.example.com and user@mastadon.example.com is this nessasary? Could u also set up a matrix account with the same user@example.com? If not what woukd be requured to change to make this possible?

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.

No, not in the example that you’ve set up. The username is always @user@domain. This is like asking if you can have the same email address on Gmail and Hotmail or whatever. You can have the same user part, but not the domain.
People that have used user@x.domain and also user@y.domain is allowed because they’re different domain names.
