Is there a way to use something like Event Bookings (http://drupal.org/project/eventbookings) or resource conflict (http://drupal.org/project/resource_conflict) to determine conflicting use of resources for an event? Basically, I have a node reference field that represents a location and I want the event creation/ event entity creation system to recognize that two events cannot be booked at the same time for the same location.

Any suggestions?
