Downloadable content

[17R3W]

While IGN has there complaints (http://ds.ign.com/articles/616/616637p1.html), it occurs to me that less content at a less crowded trade show might work really very well.

Given that Nintendo was able to fit over two minutes of video on a into a 4MB download (http://media.ds.ign.com/media/748/748615/vids_1.html) at a decent quality.

Now prevousily Nintendo hasn't wanted to let us make our content, but given that a) this is for download and not to go on there prapriatory game paks.
b) This audio/video/picture content and not games (although those were also available at E3) it would be really cool if they put out a video converting program and a wireless hosting program to run on a standard PC/MAC/Laptop.

Of course you can offer business card with your website, or even CD/DVD's with content to take home but (seeing as how kids bring there Game Boys everywhere anyway) downloading right to the DS and allowing them to view content at their leasure would be great.

I know this type of thing is coming to places like walmart anyway, so why not bring it to the masses?

EDIT: I'm confused by this video. Was it avaible for download in adition to being on a cart, or was it only on the cart?
Where there other video, and if so how long were they and what did they look like?
