I don't think this entirely will kill AirBnB. For example, I used AirBnB when doing an internship. Since it was >30 days, it was legal. I liked that I was able to read reviews, verify identities, and in a worst case scenario contact my credit card company's fraud department and get my money back. There's a huge demand for medium term sublets in SF. People doing internships, people who need a place to get some breathing room for a couple months while they hunt for a more permanent space, that sort of thing. Is it worth billions? Probably not. But I'd say it plays as useful a role as say, Craigslist.
