python raw socket / ping

[hankoifi]

Hi
I have been searching for raw socket examples for python.
Main idea is to build something like pathchar or clink with python
(activepython 2.1 , win2k and/or linux). For these i mainly need ICMP
but i also have to incrementally decrease/increase TTL-field in IP
header (like in traceroute). Found these:

1)http://www.python.org/~jeremy/python.html
  Very nice packet, includes ping, traceroute etc.
  However:  made with version 1.4 and doesn't work straight way.

2)ftp://ftp.visi.com/users/mdc/ping.py
  Only ping, but works straight with v2.1

3) couple of other ping variants using os.popen()
 ping = os.popen('ping -c 3 -i 1 ' + host + ' 2>&1')
 data = ping.read()

Number 3) is probably the easiest way to do it, but still
I wonder if somebody has already made revisions for jeremy's packet
for activepython v2.1 or otherwise got it working wit win2k
