New info on Wii Connect 24: downloadable DS demos?

In a new interview with Satoru Iwata, he sates "Turning to WiiConnect 24, which was announced at E3 as a way for the Wii platform to stay connected to the internet and communicate even while not in use, Iwata gave this example to the publication: “Let's say your Wii is connected to the Internet in a mode that allows activation on a 24-hour basis. This would allow Nintendo to send monthly promotional demos for the DS, during the night, to the Wii consoles in each household. Users would wake up each morning, find the LED lamp on their Wii flashing, and know that Nintendo has sent them something. They would then be able to download the promotional demo from their Wii's to their Nintendo DS's."
Sounds exciting!
