I would like to know if it is possible to create a multiplayer game with a distributed network
A basic example would be to move ralph in first client and view ralph move in second client with Distributed Networking (without classic server architecture)
However, revised and translated into Russian remained on our site. I think you can extract useful information. For your example of Ralph, you just need to send a command over the network - a key pressed event. As well as the direction vector.
David Rose made a sample program using the distributed system called Tagger. I have a copy of the source code; it’s was never cleaned up or restructured to be easy to read, though, but I can distribute it if you think it would be useful.
