The 64-bit version has been in the works for a while, and there is finally an alpha release for testing purposes! It sports an SMP kernel, Slamd64 11.0, Dropline Gnome 2.18, as well as a little more functionality than the previous release of the live-cd thanks to a LZMA compression. There is still more to do before the 64- and 32-bit official releases, so please report any bugs or improvement ideas. Despite the normal doom-and-gloom associated with alpha releases, I think this should work well. I've been using it as the build environment for 64-bits as well as to upload the disk image to the server (What good is a work environment if you can't work in it?). If you're interested in testing, please go to the alpha-testing page.
