Well, to start with there's your default mapper :-).  It will have
some drops but perhaps not as many.  Noel mentions caching.  I believe
caching can help a lot, but we need to simulate it.  We also need to
investigate pushing information partway, and how it interacts with
cache.  Finally, there is the possibility -- related to default mapper
-- of sending initial packets on less than optimal routes while more
direct ones are found.
