the network (100+MB) and wondering what would work better. I'm newer
to Java than I am to lisp, so I've just grabbed the most obvious
things from the API that I thought could possibly work:
(ns misc-ports

You could also wrap your input and output stream's with
java.util.zip.GZIPInputStream and GZIPOutputStream to
compress/decompress the data either side. They allow you to specify
buffer sizes, so you could
