In the client, you need to set the mode of sys.stdin to binary, 
otherwise, you get the DOS translation of linefeeds. See
http://mail.python.org/pipermail/python-list/2000-January/020463.html
for some hints.

I assume that the stream returned by subprocess.popen are also opened in 
text mode and you have to change them tobinary, see the second hint in 
the link mentioned above.
