If you need to decode this on a consumer (i.e. cheap, easy to obtain) processor and, make it simple for average Joe to use (not require an internet connection, entering a code for every use, etc.) - How can the encryption be all that good?
People looking to steal and resell you data from will have machines that are fast enough to crack it in a relatively short time (brute force crack using a cluster, may not be pretty or efficient, but some major crunching power can be put together on the cheap.) If it can be viewed, there is some way of copying it - quality is not the highest priority of "pirates." It may prevent casual copying, but that could be accomplished for much less.
Who are they trying to protect their work from?
I am a mechanical engineer, I know nothing about encryption, DRM, or how it's done - So I may be completely wrong with my thoughts on this subject. (Please correct what I got wrong.)
I put together a mythtv system from an old computer; it was a way for me to learn more about linux.
But, then after the motherboard went bad (bad caps.) I bought a new motherboard, processor, and memory ($159.) It wasn't "pretty" enough (girl friend didn't like the case next to the TV.) So I bought a silver stone case and power supply ($190.)
Can't forget the two tuners; pvr-250 ($120) pvr-150 ($60.)
Total $529...
My ReplayTV, refurbished 5040, $350/with lifetime service.
I paid $179 more for a homemade pvr and some linux experience. Not to mention a fun and frustrating hobby.
I think it was worth it, but my girl friend prefers the replay.

I agree, I was just throwing in some numbers in for an "ideal" case. The real cost saving over a year wouldn't cover the card.
I have found over the years with each upgrade the designer makes bigger (longer to render) models, and the software get bigger (OS, MCAD, PDM,...) The ROI doesn't come from modeling faster, the ROI comes from better models. That is impossible to measure (and my not have any real ROI)
By the way... when I'm waiting for my model to render - I read slashdot;)
I am a CAD administrator, and use several different CAD packages. The problem I have with most graphic card now isn't performance - it's accuracy. When you zoom up on an intersection and the lines "move" at different zoom levels, it becomes impossible to know which surface is which.
I have had this problem with Quadro cards. I have not had a chance to try ATI cards. I have had the best results with older 3D labs card (gx1 pro and gmx 2000.) Those cards did not offer the fasts performance, but were better for surfacing.
Where performance matters is when I'm working on large assemblies. Some of the repaint/redraw times can be as high as 15 minutes (1.8 GHz, 1 GB RAM, Quadro 550, Pro/Engineer, Windows NT)
I would love to give Pro/Engineer a try on Linux (It's available - web site is ww.ptc.com) But, our PDM package (Pro/Intralink) is not. Does anyone know how the performance compares to Windows?
I live in the Pittsburgh area, they are running an ad program, "Stay, invent PA". It's about the great techie jobs in the state, and begging you not to leave the state. Now they pass laws like this?

The problem isn't scale, it's strength at scale. I have worked with machine like this for a couple of years now, we have used some of the thicker (no section smaller than 1/4") to test designs. The powder-binder (z-corp) machine break or warp at smaller scale, "glue gun" (Stratasys) become flimsy, SLA (laser-thermoset plastic) break or warp.
Also, when large part are scaled down to fit in the build volume (i.e. 1/12 scale model of a train) wall thickness becomes a nightmare. A 1/2" thick body shell become paper thin.

Ok... ROI - At 10% faster....
The burden rate for our CAD designer is ~$60/hour
(We use Pro/ENGINEER - could take advantage of the card)
2000 Hour/year x $60/hour x 10% = $12,000
20% of the designer's time would have to be spent waiting on the graphics to pay for the card.

It cost me $40 just to go to the company party!
The company did kick in about half for the party, and they had door prizes. But, no one got a bonus. (or, no one at my level got a bonus...)
Every time I read something like this it pushes me one-step closer to buy a PVR.
One or two more lawsuits and I will buy one, who make the best PVR for the money?
Oh boy! Now I can have free access while I sit in my car due to all the road construction!
