Can I install or copy the medium to my hard disk? No, the software is only designed to boot from a live medium.
However, as the live DVD is said to be based on Arch Linux I think it is pretty much possible to put it onto the hard drive. A painful way to do this would be to install Arch and try to make it look like this DVD. The download page says that the ISO is isohybrid, I don't know if it makes any difference.
Is there a (reliable) way to turn an ISO like that into a working installation? I wouldn't mind spending a few days to mess with it.
