Okay, sounds good. I'll set up a wiki branch of my git repo mirroring it.
I was going to ask you to reorganize the directories so that they'd work better for mirroring, but then I realized it was a wiki, and did it myself. I hope you don't mind.
Update: There now exists git://nex-3.com/arc-wiki.git, with anonymous push access.
You don't even need a fake username-password :). It has all the patches in the Subversion wiki as of this writing, and it's based on my existing git repo, so patches can easily be sent back and forth.
