[Discuss-gnuradio] Implementing A/D in FPGAs

As you probably know Hollywood is frantically searching for an effective means to plug the "analog hole" between consumer video components. A while back they formed the Content Protection Technical Working Group http://www.cptwg.org. I came across an interesting article today on that web site and thought it could stimulate some discussion for future board designs.

The article, "Myths and Misconceptions about Hardware Hacking," http://www.cptwg.org/Assets/Presentations/ARDG/ARDGHardware_hack05-28-03.pdf offers some interesting insight into the current capabilities and trends of hardware hackers. A particularly interesting item is the ease with which relatively high performance Flash A/D converters can be constructed using external resistors and the LVDS comparators inside the FPGAs. A 6-bit, 10 MHz+, design is offered. Is anyone here able to offer a competent analysis of how practical this is for some of the applications being discussed? How far can one reasonably extend this to higher bit depth and speed? Is it cost/performance effective?
