I was playing around with the "Vendor" portion of the Hippotech Rental System, and although using a vendor to market rental spaces doesn't appeal to me, it does strike me that it could instead be co-opted into functioning as a directory of shops, public places, and even (if people wanted) private homes.
Essentially, the "vendor" pages through pictures of each rental parcel, and when clicked, can show the map location / set the red "Beacon."
In the future, when the little boutiques, parks, art galleries, and whatnot are ready, perhaps I could load the "vendor" with pictures of each shop, and the display placed in the corner of a central, public place.
Just an idea.
