FYI, WiiConnect24 is not an online networking service, some of what you describe applies to Nintendo Wi-Fi Connection. In particular, WiiConnect24 does not allow for online gameplay, only Nintendo Wi-Fi Connection does.
There's a big difference in the two services.

You're right, WiiConnect24 is for updates, messages etc even when in standby.

I've corrected the list of games, but the description could be improved. Pepsiman 04:55, 23 April 2008 (PDT)
