why do you say that a module can only be installed in only one server? For me, UNA can runs on the cloud, each module can be on a different server or usinjg microservices in docker, and if I want I put each module on ten servers, and another less used module on only one server. If I want, I run messenger on 100 servers and the rest of the site on one., photos on another server, videos on another and css and js on another. Nothing is impossible. nginx can run any folder on another server, in any location on the globe, I can put a location on a server in Australia and another folder with another module in another location in the USA or run one module in 10 different locations at the same time to serve other users with a load balancer.

I only want from you the source code from messenger, you boasted that you published it here, but your links are not functional they all go to the same location.
