    receiving, at the first availability service, the real time availability data of the type that is retrievable by the calendaring application for the first potential meeting attendee of the one or more potential meeting attendees, wherein the real time availability data indicates whether the first potential meeting attendee of the one or more potential meeting attendees is free or busy for the specific meeting event;

    receiving, by the first availability service, the real time availability data for the second potential meeting attendee from the second availability service; and
