Sounds like a good opportunity for AirBnB to standardize and develop a specific hardware implementation for this similar to Amazon's locks. My initial impression is that AirBnB wouldn't be interested in taking on that risk, but then again I'm surprised Amazon is willing to take it on since they have so much less to gain than something like AirBnB. AirBnB is much more like the other sharing economy services, where the only thing they provide is the marketplace and connect the supply with demand, however this is an awfully low bar and therefore invites competition. My hope is that, gradually, these sort of companies will transition into more of a franchise / partnership model, where they provide more support for the suppliers. A standardized way to get access to the property is one simple example of a benefit to all parties.
