I like the idea of having a terminal in every Pokecenter to tell us how to evolve a certain pokemon. I am with the others on the fact that the trading mechanic to evolve from an NPC has always been rejected before, but I would definitely like to see the idea of telling us how to evolve all pokemon. Overall, I would say that without the trade part, this is a great idea and would help prevent many questions on how to evolve certain pokemon in the help chat.
