Fair point. If you own the condo or house that's being AirBNB'd, then we're ok (modulo pissing off the neighbors). If you're renting, then we're getting into the same territory as "unlimited bandwidth" subscriptions for ISPs or cellphones. Landlords -- reasonable, non-legalistic ones -- might then want to specify the maximum number of "person nights", etc., since all of a sudden "having a few friends spend the night" (taking the # of occupants over the lease maximum) becomes a permanent thing. It's a little like a tenant who takes a dozen showers a day, every day for a year. Leases don't generally specify the maximum number of showers permitted, but they might begin to do so. So, it could be workable, if the various contractual arrangements could be adjusted. Disclaimer: I'm a (small-time) landlord.
