This is probably the best approach. Provide a struct from the packet and
ask for a struct back. My C is not so bad that I couldn't write a simple
decoder for a simple protocol like Ident or Finger in that environment.
Would be great to have a couple of modules to start with/look at before
trying to write my own. Maybe one for POP and another for HTTP would be
enough to show enough complexity (since POP is chatty and HTTP has
binary transfer, the two are at opposite ends).
