I noticed this.. it's great news not for Flash only but all 3rd party
video playback applications (XBMC, etc.).

Not without a browser hook. But that's the 'easy' part, and I think
this is Apple's first step towards hardware accelerated HTML5 video.
Just guessing, but they probably have that work done already for
Safari. This looks like a bone tossed to Mozilla and Chromium devs,
more so than Adobe (like all the news sites are making it out to be).
Just my 2c.

This is almost confusing. So the first paragraph eludes that VDA
provides support for certain Nvidia GPUs, and the second more than
contradicts it.
Linux has VDPAU which does the same thing for Nvidia and goes as far
back as the 8500 GPUs. Or there's VA API for Intel chipsets. Or XvBA
for ATI chipsets.
These are all open source APIs provided by the above mentioned chipset
vendors themselves.
Maybe Adobe feels this is too much work. But they have always given
Linux the short end of the stick anyway. I just don't like the BS line
of 'no standard API' when they could implement VDPAU and have more
than what Apple seemingly offers for their platform, right now.
