ISO-only? (Score 1)

I have a problem with a distribution (prerelease or final) that is available for download *only* as an ISO image. Looking at the screenshots it says that installation from anything other than CD is currently unavailable. I'm not that anxious to burn a CD just to take it for a spin, and having to hack on the installer myself defeats half the reason for getting a distribution instead of rolling my own. Since the other options are there in the screenshot, I'm guessing that they will be around in the final release, but will they actually work the first time?
