Caldera is probably best known for going against the grain in the Linux world and is the first Linux distribution to introduce per seat licensing. Version 3.1 has made a lot of advances such as full OEM testing, but is it worth the per-seat licensing?" Is this any different from other distributions' "power packs," which bundle Free software with proprietary? According to the Caldera site, you can download the ISOs as well as the source to the server and workstation varieties of Open Linux on a (eh?) "single, non-commercial license."
