Since the download for the Linux tarball has been taken off the main server (for understandable reasons) it would be nice to have some alternative mirror allowing direct linking to the file. In case you're wondering, I'm the maintainer of the Open Arena Pkgbuild for the Arch Linux distribution (
http://aur.archlinux.org/packages.php?do_Details=1&ID=7748), and Arch's package building mechanism needs a direct link. Certainly every OA-playing Arch-user (including me) would be grateful :-)
