Use your favorite bar code scanner app and add the Ubuntu Countdown Widget to your Droid home screen. Bar code located near the top tight of his blog.
Last week I created a new page called Apps on my Droid which contain most of the apps on my Droid. Instead of using a link or entering a search in the Droid Market, I posted the 2D bar codes which links directly to the app.
Just install a bar code scanner on your Droid and you can install apps from any bar code.
