I haven't any interest in hacking my Wii to play homebrew stuff, but it's still neat that you were able to pull this off. ;)
The release of the game most people will have does indeed have multiplayer support which is essentially deathmatch across special multiplayer-specific maps. I actually tested it and recorded some multiplayer footage of Abuse when I was making the ADG episode, but I didn't show it because it just amounted to me controlling one character while the other sat there motionless. It only works over IPX so I'm not sure how you would even attempt to get that working on the Wii. :/
And yes, the editor does have some special controls over the main game... Too many to list. >_>;
