Agreed (though I've no idea what a UK (?) pound is worth. 1920 x 1080 x 24 bits per pixel x 24 fps = 145MB/sec (not allowing for audio) I suspect there would only be two types of user for the key - vendors of home entertainment systems "might" become a market (though they already use a system to bypass restrictions on projectors), and commercial pirating operations (the ones who actually press disks). Though the articles I've read all talk about pirates I suspect the reporters are just *cough* wrong (pre-release pirate material is copied from studio prior to encryption). I recall reading an article by a Google engineer where he spoke of a (Linux) system using multiple off-the-shelf computers with software (?) RAID to achieve near-RAM speed disk access - and an evaluation FPGA card from www.xilinx.com is fairly cheap... With reference to the original posters question - maybe, just maybe, the key might become part of a driver to allow any display to display a stream from a blueray player... but I won't be writing it. I'm very happy with the performance I get by simply copying the bluerays I buy to hard drive, and I prefer keep my media on hdd.
