Multiple Player Prefabs in Unet

So, what I want is for each player to be able to choose what they will spawn as after they connect.
So far, I can't find a way for a player to control an object that doesn't spawn immediately as the default player prefab.

I know this is a somewhat common desire, and has solutions, but I can't find any sample projects.
I have a very difficult time understanding contextless code snippets or abstract document references.
If you have or know where to find an implementation, it would be much appreciated, helping me and others.
