I find WiiConnect24 an interesting challenge: it isn't straightforward.
It merely means that players can be always connected to the network. This is not a persistant world, just a persistant connection. This has applications for things like getting mail 24/7 (animal crossing) and for episodic gaming (your idea MaryJane)... and actually even shares traits with Nintendo's Super Famicom Satellaview system, where players played a special edition of Zelda: Link to the past only at certain dedicated times and with real-time narration over broadcast, playing the game regularly in set-time segments with a narrator describing what was happening in the entire game, no matter whether the player was cutting grass or actually getting closer to the storyline... (if you missed the broadcast you didn't get to play)
Hmmm....
If you're always connected then the gameworld can change at any moment... if the gameworld can change that means that reality in the game can change... assumptions can be challenged, storylines can twist, bad things can turn useful, friends can turn hostile, and gravity can turn upside down. And all of these can change the realities of what the player has done IN the game, as well as change their plans for the future.
For example, suppose the player is interacting with NPCs. They want to build up a friendly relation ("rep") with certain npcs or groups of npcs because these groups are helpful(maybe they can get you free gas on a world where gasoline is a luxury?). BUT, when the next WiiConnect24 update comes out, it changes the game's environment and reality and makes your "friends" liabilities. Their benefits no longer help you (all of a sudden energy becomes free and gas becomes useless) , and your association with them may actually make things harder for you(people want to persecute the people who had the power (and the gas) before).
OR... maybe dial all that drama down a notch or two?
Merely make it so player's have to plan a course of action several days in advance. They make a plan to infiltrate a facility in Moscow. But on the day of the attack, WiiConnect 24 gets the weather report to discover that it's actually snowing in Moscow. All of a sudden the player has to react accordingly?
Or... maybe a stock trading game... The game follows closely the real ups and downs of NASDAQ. And whether the Nasdaq is doing well or whether it is doing poorly makes npcs in your game act in different ways, some get happy, some get more risk-happy, some get desperate, some cross ethical lines, etc.
Maybe Wii Connect 24 can allow RPG players from far away influence each other's games. Just like Spore let's players put their species up on the itnernet for other games to use as alien species, so that players are exposed to each other's creativity without ever directly being in contact, or just like Pokemon Mystery Dungeon lets you "rescue" from long distance a friend who got pwned in his dungeon, actually affecting another player's game world despite not actually existing in the same exact game world? Hmmm....
Maybe in an RPG, itf you wanted to change something, you'd ask somebody in another RPG to change it for you by doing a mission in their game. Let's say that you want to put out a hit on an enemy character, but you don't want the blood on your hands. Make up a contract and send it out over the WiiConnect24 service. Then someone will accept the contract and time limit and do that hit for you, and get paid accordingly in their game. In your game, you're a little poorer, but your enemy figure has been killed, something you, for RP reasons, were unable to do...
Hmmm...possibilities...
