Hi Joel,

I've been working on a library to parse binary data files (java bytecode 
in my case), and I ended up writing my own DataReader monad for the 
purpose of reading binary streams.  It offers two main features:

  * It keeps track of how many bytes you've read.  This is necessary for 
reading java bytecode, but probably unnecessary for the protocol you're 

  * It supports hierarchical error messages (so you see "error while 
reading foo: unexpected end of input" instead of just "unexpected end of 

If you're interested, you can check it out here:
