While locking and security MAY be futile, that sure hasn't stopped people with extremely deep pockets from trying everything in the book to prevent you from stealing a pristine original digitally-exact duplicate of their content. Case in point: Blu-Ray and HDCP
Yes, all the protection fails when it is finally displayed on a viewing device, and it is possible to capture said image by pointing a camera at the screen, but the resulting copy is not a digitally perfect copy and results in analog-to-analog capture deviation, optical distortion, and recompression artifacts. So it is not a pristine original digitally-exact duplicate of their content. I have already discussed the idea of a 3D card with similar DRM protecting its texture memory and an interal workspace on this list and I won't go over it again. But the real point here is that all this "useless DRM":which may "get broken someday anyway" (as say the naysavers) is expensive to implement. The cost is high and is a huge financial drain to develop. The knowledge of how to work with the protection must be shared with outside manufacturers who may be sloppy about protecting the work, and any one of those idiots can be responsible for undoing the whole thing. (This is how the DVD deCSS got started.) Note that both ATI and nVidia are complying with the music/movie industry DRM controls on digital data streams and HDCP. I don't think the MPAA/RIAA can FORCE either video card manufacturer to comply, but they can pay the manufacturers for their time and effort to implement such DRM controls. So the real question is, how deep are the pockets of Linden Lab and other online worlds developers to create such DRM protection and controls, and how much financial loss due to hacking of their DRM can they tolerate? I don't think the Lab's pockets are anywhere near as deep as those of the movie and music industry, nor can they provide "influence/fees" needed to get the likes of ATI and nVidia onboard, so that kills any such "3D DRM" controls straight off. So in summary you won't see 3D DRM because LL isn't willing to spend huge sums of money on trying to implement what is an "ultimately futile" effort to protect your content. And really it all comes back to the content creator. These controls if they existed don't need to be freely given to you. LL might charge you a large recurring fee to protect your content. I am sure the MPAA isn't doing their Blu-Ray protection out of the goodness of their heart for content producers. No, the MPAA is charging them a huge amount of money for the use of the protected distribution channel, to pay the MPAA back for their time and effort to create that channel. Would the copybot haters be willing to shell out a huge expensive annual fee five times higher than their land/server rental fees to get their content protected? (LL would in this scenario intentionally expose your content via unencrypted HTTP that is ripe for the picking, unless you pay up for the protected channel.) Oh, I bet that would finally stop this topic dead in its tracks, if the "copybot whiners" actually had to PAY say $10,000 a year to LL, on top of their land/server tier, to have their digital content protected with 3D DRM. :-) - Dale Mahalko / Scalar Tardis On Mon, Sep 14, 2009 at 9:31 AM, Tateru Nino <[email protected]> wrote: > In summary (and I think this topic is beyond the scope of the list) the > following things are true: > * At some point, unlocked content must become available.
