Each member in the ZIP file has a header, so you can read the members 
without reading the header first. The JDK has a class that reads a ZIP file 
from a stream:

  http://java.sun.com/j2se/1.3/docs/api/java/util/zip/ZipInputStream.html

Also, HTTP 1.1 has byte-ranges, which means, at least using HTTP 1.1, you 
don't have to download the entire zip file even if you need to get the 
directory.
