Thanks for the link, more food for study on how to write a generic
library...
Basically, I am scheme/lisp noob, learning it in my spare time, the
progress is slow but rewarding...
Few obs

Not sure if this will help with what you are working on. I ran across
a similar problem last week and ended up writing a generic library
that converts various sizes of integers to big or little endian byte
arrays and then back again.

In general, Writers are for character data and OutputStreams are for
binary data. If possible, create a FileOutputStream like this:
(ns my.ns
(:import (java.io FileOutputStream)))
(def ofile (FileOutputStream. "/some/file/somewhere"))
and use one of the write methods of FileOutputStream.
