good list for /etc/hosts

i'm not coming down on either side of the 'ads are good' vs. 'ads are bad' topic, but for people with lower bandwidth who like to kill the known ad-serving hosts, here's a great script to update your hosts file and get an updated list from the net periodically.  i've posted it below, (note: std #! explosion disclaimer applies)  if i can find the original source, i'll link back to it. it's set up pretty simply, so you can change the script to whatever source you like to use (i know mvps is popular.)

#!/bin/bash
# Hosts file updater
# Originally written by Andy Short circa 2002
# You will probably need root or su rights to access /etc/hosts
# modified by killermist with (what seem to be) some logical tweaks
# 20090712 alfredo (1) Added checks for required applications;
#                  (2) put 'footprint' text into the modified hosts file.
# Debian users will need the package "sysutils" as this script uses dos2unix
# $ sudo apt-get install sysutils
#
