Lets a business share docs from their Microsoft SkyDrive over SMS via Twilio. Go to the app which is running on Windows Azure, set which SkyDrive account to use, and select a public file to share over SMS. Customers (incl. potential customers) can call the Twilio number associated with the #docs deployment and text "link" to get a link to whatever doc you're currently sharing (for deals, specials, marketing info, etc.)
For the sample #docs deployment, call my Twilio number (415)599-2671, enter passcode "7392-3266", and message "link".
