Ah yes, the infamously bad UpdateLayeredWindow API documentation.
The idea is that you provide DC in hdcSrc, which contains the bitmap information of the window. You'd want to premultiply the alpha channel with the RGB channels. Windows will then take that and composite the bitmap with the underlying windows.
Admittedly it doesn't provide the same sort of OS support that OS X does and is horribly slow for large windows, so it's as good as non existent. OS X allows you to do things like stack 20 translucent command line windows over a video without any reduction in frame rate, but XP can't.
It's not open source, but they do support Linux. They claim to have succesfully located and unencrypted the white balance information. As far as I can tell they do not use the Nikon SDK.
As a Nikon shooter I don't really see what the fuss is. I bought the D2H last year, and the extra cost of the software is just like any other Nikon/Canon accessory (e.g. the $120 strobe cables).
Unfortunatly, this isn't the holy grail of digital camera. I'm not even sure what the holy grail would be, to be honest.
It's a very specific camera aimed at sports/news/action photographers. The Wifi addition is also a niche product, mainly for photographers in large agencies like the AP
It probably wouldn't suit anybody else, especially since most people complain about the 4mp resolution.
Personally, I'm excited because this is the first Nikon DSLR to do 8fps, plus they have a new TTL flash system, and the 2.5inch LCD on the back is the biggest yet (great for "chimping", a term for gaping at your images instead of watching the action)
Digital SLRs have excellent battery life, normally. The Nikon D100 (a consumer DSLR) can happily take 1000 photos on a single charge, in real life applications. You can also add a power grip which takes 2 of the D100 proprietary batteries - you're not likely to run out of power in a week.
The D2h has a newly designed battery, and whilst nobody has tested it yet, all the specs point to it being better than the old NiMh batteries used in the old D1 series cameras.
I'm certainly interested in a Windows port - as for helping, I use Delphi which will probably make collaboration difficult (when it comes to coding).
One idea you might want to consider is having a start and end parameter sets, and using GJay to slowly morph the playlist (eg, starts slowing, chilled music, then slowly getting faster - etc).
Btw, how well does GJay work with massive audio collections (say, 1500 albums, ~15000 files)?
Foobar 2000 for Windows has been able to play OGG FLAC files, which are FLAC encoded files in the OGG file wrapper format for a while now (since it was released in december 2002), so it seems this partnership is slightly more than just political.
Your specs seem to refer to the TX-NR900 reciever. This does not run Linux, it merely plays music from a network connection. I don't think Linux is required for such basic functionality.
The Integra NAS-2.3 Net-Tune Server is the Linux based product. It's actually a rebranded Imerge product, from the UK. You can control the server via a TV, Monitor, PC, Palm, IR Pronto etc... Check out the LCD, it's just a bog standard LCD display used by many case modders - not a custom built VFD display as found on most hifi components.
The Integra is really a rebadged Imerge product, who are based in Cambridge. It is known as the SoundServer S2000 - http://www.imerge.co.uk/products/improductshtml/ip main.html
Of course, there may be some functional difference, but otherwise they look identical. Costs £1599 - AS this is Slashdot, I bet most people would just build their own audio server PC and slap in a nice sound card (M-Audio Delta 410 audio card offers slightly better specification) and with some interesting software, you could have a relatively cheap multi-room audio server which supports say, OGG Vorbis, APE, SHN, etc.
If you've seen a video called "Deadly Weapons", used by training by many police departments, they demonstrate the effectiveness of bullet proof vests... on live subjects.
They used an assault rifle, at point blank range, and the human subject is totally unharmed. Additionally, the subject stood on one foot, and didn't fall over.
The vests were rather chunky, however. I'd rather have one of them, than some paper thin vest that fits under my shirt.

Just in case you didn't see my other post:

The Sonique-Mantis demo and Winamp3 both demonstrate realtime per pixel alpha layer manipulation in real time. They're pretty cool.
Hmm, actually windows does support per pixel alpha - I wonder how it manages all those things like menu shadows.
And here's a screenshot of it in action:

Bibble Labs announced that they will be supporting the D2X encrypted NEF white balance in their Bibble software:

How well does GJay work? I'm a poor Windows user so I can't try it out.
In particular, how well does the frequency fingerprint help in identifying similar music?

I personally think that it's 100% off topic, and you've shared your experiances more than people care.
Apparently the recent G4 computers aren't very quiet - and people have started referring them to as "windtunnels"
