Airbnb is in a prime position to expand into the market of web-based PMS (I'm not kidding -- Property Management Systems) that are super expensive and still run on old MS-DOS machines in many hotels. Give hotels a web-based solution that interfaces with hotels.com and other sites (there's a rather involved protocol that you need to license, but the name escapes me) and you're in business.
