Non HW: Max 4 uses it. I have yet to find a crack but that's not to say that it hasn't or won't be done. It's been out since around January. Pixels 3D seems to be successful with a similar scheme. I've seen cracks for older versions but keep in mind that as this technology advances, it will become more and more difficult. Both make it much more difficult to obtain additional uses for serial numbers. And again by successful I mean curbing warez. We won't make you jump through hoops. **************************** Steve Yatson Product Manager Curious Labs Http://www.curiouslabs.com ****************************
