I made this request in the bug, but I figured it would be good to post here as well. I've posted a patch to Bug 7929 (C&C 3 network does not work) that I believe addresses the concerns people have addressed over previous attempts to fix the issue. So, I would like to request that the bug be re-opened and for people to take a look and comment on the patch.
