I wrote some code about 6 years ago where I was able to read 
gzip'-compressed a byte at a time. While it is true that you have to get 
through the GZip'd file at least as far as the compression headers, once 
you get past the headers and to the actually compressed content, you can 
read that content in a progressive manner. In particular, you don't have to 
do a complete batch unzip before you can parse the first byte. When I did 
this, I was using public domain gzip software.
