This first approx of python code

Spoiler:

#!/usr/bin/python2

__author__ = 'axa'

import zlib

ZLIB_MARKERS = ['\x78\x9c']
filename = 'nickel-glo'

infile = open(filename, 'r')
data = infile.read()
end = len(data)

pos = 0
found = False

while pos < end:
    window = data[pos:pos+2]
    for marker in ZLIB_MARKERS:
        if window == marker:
            start = pos
            rest_of_data = data[start:]
            decomp_obj = zlib.decompressobj()
            uncompressed_msg = decomp_obj.decompress(rest_of_data)
            print "===== Message start %0x\n%s" % (pos, uncompressed_msg)

    pos += 1

There is a bug, but the result is very interesting.
