I had no trouble creating a zip file from a 4GB file filled with '\0'
bytes:
$ python bennie.py
$ ls -ls test.zip big
12 -rw-rw-r-- 1 jepler jepler 4294967296 Mar 20 14:11 big
4084 -rw-rw-r-- 1 jepler jepler 4174545 Mar 20 14:14 test.zip
I'm using Python 2.3.3 on Fedora Core 2.

def make_4gb_file(f):
f = open(f, "w")
f.seek ( 4 * 1024 * 1024 * 1024 - 1)
f.write("\0")
f.close()
import zipfile
z = zipfile.ZipFile("/tmp/test.zip", "w", zipfile.ZIP_DEFLATED)
make_4gb_file("/tmp/big")
z.write("/tmp/big")
z.close()
