libapache2-mod-scramble-ip is an Apache 2 module
that works like mod_removeip, but instead of just
overwriting the IP address with 127.0.0.1, it
encrypts the IP address. This way you always get
an IP address to work with (in scripts, etc.) and
have the ability to use tools like awstats to
analyze your logs. It's in alpha status, but
working on some Apache 2 servers, and the 'cost'
(load) should be small and reasonable.
