Like TurnKey so much you want a local copy of all the appliances but too lazy to download individual appliance images from SourceForge by hand via browser?
I know exactly how you feel. Sloth is a virtue, and in the beginning was the command line.
So now you can use rsync or ftp to batch download the entire virtual appliance library in whatever build type you like best from a high-speed mirror near you. The way the net gods intended!
