I actually need little endian encoding... wondering if anyone else hit this with Data.Binary. (because I'm working with Bell Lab's 9P protocol which does encode things on the network in little-endian order). Anyone got some "tricks" for this?

You could just define data type and Binary instance for 9P messages. Something like this: P9Message = Tversion { tag :: Word16, msize :: Word32, version :: String } | ... instance Binary P9Message where put (Tverstion t m v) = putWord16le t >> putWord32le m >> put v -- and so on... get = do length <- getWord32le id <- getWord16le case is of p9TMessage -> do ... There are a lot of boilerplate code thought... BTW could you say what do you want to do with 9P? I tried to play with it using libixp library but without any success. It was mainly to understand how does it works and how can it be used.
