Yeah, but it's still quite a bit better than the previous situation
where the hardware capabilities were not available, hardware specs
were only available to NDA agreeing big-money partners.
At least with this, a motivated group of developers can give it a try.

For proof that the seemingly impossible development task can be
accomplished, just look at MythTV.

The other thing is, these GPUs are remarkably powerful.  Once a
programmable GPU is brought into play, you can easily see some cool
scaling, de-interlacing, and other post-processing being done.

I'm sure it will take a while.  But, the potential is exciting.
