I've talked to a few startups doing interesting things like loading building designs into 3D game engines and letting real estate agents meet and talk with potential investors/buyers in the space itself. This sort of thing normally gets done by phone, Skype, pre-rendered videos, or rare and difficult to arrange trips to the site or design offices. If an investor is visiting from China and only in the US for 10 days and is checking out a dozen different hotels to fund building, there just isn't much time on the trip side of things. So there's lots of room for improvement.
