OK, so it's not the most exiting way to start a blog, but....

 A while back I wrote an apache module to prevent IPs of web site users being recorded.  The module over-writes apache's information on remote IPs and hostnames before things like cgi and php get run, and well before logging occurs, making it look like all connections come from localhost (127.0.0.1).

A new version which works for Apache 2.0 is now available from:

http://conway.cat.org.au/~andrew/mod_removeip-0.2.tar.gz

This module does nothing untill you load it, and enable it with the only command it understands:

REMOVEIPenable On

At that point, IP information becomes unavailable throughout apache.  Ie it affects all virtual servers, all directories, etc.  In CATs case that makes sense, because CAT, like many indymedia hosts has a policy of not recording IP information of web browsers at all.  If someone wants finer grained control, they should get in touch with me about it.
