If you want the compiled rpms (much easier) you'll have to get them out of the ISO for SME 7 Beta1 here: http://distro.ibiblio.org/pub/linux/distributions/smeserver/releases/7/iso
Nope, they're here: http://distro.ibiblio.org/pub/linux/distributions/e-smith/devel/repo/RPMS/
This directory might not always have the latest version though. Any updates probably will be in the smeserver directory later on. The project is now at http://smeserver.sourceforge.net
