A Live Map where audience can drop markers

Add markers to map, remotely!

Let's assume that there is a bunch of people in an auditorium. We open http://this.stuff/map on a big screen. There are already some static data-dependent markers. Some clutter is removed from the map. Now, everybody can start adding markers by opening http://this.stuff/ on their devices. Nearby markes are grouped and counted. Markers are not persisted, just kept in memory to survive the map reloads.

Hardcoded for a specific event. At minimum, it is necessary to change location selection geo-limits, hardcoded locations, strings, language preferences, Google API keys.
