I wonder Zillow could do market making without the actually buying and selling that introduce so much of the risk. Gather into from prospective buyers about what they're looking for and identify houses that are a good fit and serve them up to the buyers. Not sure how to monetize, but this is essentially cannibalizing realtors, which is always where I thought their business model was going in the first place.
