Don't know about other people, but I'm a little cautious about downloading and installing software on my computer. Was kind of hoping somebody else would have been more adventurous. You didn't really give much detail on what it does, or why anyone might want it. Aside from potential virus concerns, it's also an Alpha version, which usually means it hasn't been tested on a lot of other hardware. I don't know much about Vista, and hoping I don't have to spend much more time learning to keep it running.
