This is based on tauren's answer, but includes the necessary date math and fullcalendar selectors to pull it off (this code uses a range of 12 months):

jQuery('#edit-calendar').fullCalendar({
    viewDisplay   : function(view) {
      var now = new Date(); 
      var end = new Date();
      end.setMonth(now.getMonth() + 11); //Adjust as needed

      var cal_date_string = view.start.getMonth()+'/'+view.start.getFullYear();
      var cur_date_string = now.getMonth()+'/'+now.getFullYear();
      var end_date_string = end.getMonth()+'/'+end.getFullYear();

      if(cal_date_string == cur_date_string) { jQuery('.fc-button-prev').addClass("fc-state-disabled"); }
      else { jQuery('.fc-button-prev').removeClass("fc-state-disabled"); }

      if(end_date_string == cal_date_string) { jQuery('.fc-button-next').addClass("fc-state-disabled"); }
      else { jQuery('.fc-button-next').removeClass("fc-state-disabled"); }
    }
});
