[Haskell-cafe] Data.Binary.GetT or ... ?

I'm thinking about using Data.Binary to parse binary stream of data.
Binary data stream consists of messages which can have one or more
(sometimes couple of hundreds) sub-messages. The stream is spitting out
I would like to parse this data with Data.Binary.Get monad, but I would
like to send sub-messages to a STM channel while parsing, so "observers"
could handle them during parsing process.
I believe I could achieve this with a Data.Binary.GetT transformer, but
I'm not aware it exists.
Implementing GetT would take me a huge amount of time (I'm not that good
haskeller). Splitting processing to message level and sub-message level
and handling them by two separate "get"s in IO monad is a possibility,
but not really appealing one (at least to me).
Is there another (preferably cheap) way of doing what I want?
