I use WowAceUpdater and from what I can see, it seems, that it generates a lot of traffic. As I have few servers at pretty good line I thought I could offer a part of it to the project. WAU seems to have mirror support and from what I understand it works on top of HTTP/SVN so it should be no problem to create a mirror. Would the community benefit from this, or is it just a pointless offer?
(i can help mirroring anything else you might imagine, it just seems to me, that WAU is the one that needs it most)
