In addition, the polyparse library provides "online", or lazy,  
parsing.  Its interface is somewhat similar to parsec, perhaps even  
simpler.  (Actually, you can freely mix lazy and strict parsing -  
laziness is provided by applicative combinators, strictness by monadic  
combinators.)  I have not yet looked into whether it would be possible  
to link polyparse to iteratees.
