This is method I've come up with:

     def getNextEvent(self):
         """ Get the next event from the calendar"""
         today = DateTime()
         print today
         query = self.portal_catalog(
                     portal_type=self.getCalendarTypes(),
                     review_state=self.getCalendarStates(),
                     start={'query': today, 'range': 'max'},
                     sort_on='start')

         def sort_function(x,y): # this should be a utility method  
for the class
                                 # as indeed should the check for  
uniqueness
             z = cmp(x.start,y.start)
             if not z:
                 return cmp(x.end,y.end)
             return z

         rids = []
         results = []
         for result in query:
             if not result.getRID in rids:
                 rids.append(result.getRID)
                 results.append(result)
         if results:
             results.sort(sort_function)
             return results[0]
         return None # probably unnecessary

I've also written a simple next_event_view script and  
next_event_view_template
I'd write a test for this but I've never written a test so it might  
go horribly wrong! ;-)

If you wish I'd be happy to submit this although I think the changes  
for unique results and sorting should also be reflected.
