Hey! That shouldn't be much of a hassle if you know how to handle peer X and Y cordinates. Just make sure that every player has some internal value that indicates current state and always sends it to the server. If your player is staying still let's say you send 0, if he is running set it as 1, if jumping send 2. You get the idea ;). On the receiver side you set this value to the specific peer and assign correct animations accordingly. Best of luck with your implementation!
