Democracy Plugin and HTTP Proxy

In order to speed up my site, I’ve implemented Varnish to help. However, there’s a problem with my Democracy plugin, since I have it logging IP addresses to prevent poll-hogging.

The way the server handles IP addresses is different now. I had to patch my comment.php file in order to show the proper user IP address when a comment is made.

However, the Democracy plugin now stops after one vote has been submitted (because it thinks every user is on the same IP address).

This is the patch a consultant helped me on the user side, can anyone help me patch the Democracy plugin to again allow votes from more than the first user to vote?

Please advise.
