I just found a useful addon, not for the droid itself, but for Firefox, which will generate a QR code for whatever site you are looking at, which is very useful for downloading items to your phone such as the wallpapers on this site: browse on your computer, grab the barcode, save to your phone.
The addon is called Mobile Barcoder, and is available from https://addons.mozilla.org/en-US/firefox/addon/2780
