I seem to remember a scene in Babylon 5 where Vir got sick eating at a place that sounded like a rebranded McDonalds. Londo was chastising him saying you know Centauri stomachs can’t handle fast food. I wish I had time to rewatch that show.
I’m short on time, but here’s the general idea. Telegrams front end, the part you use I the open source part. The backend is the closed off part. The two parts are separate but communicate via a protocol, kinda like email. The forked project can change anything they want, to make it do whatever they want, but it still needs to be able to speak to the backend server.
Off course! Though I bought the CD and ripped it. Dangerous and Moving was a great album.
It sounds like a decent way to fund a server. It’s not something I’m interested in, but you might get some takers.
