Hi guys, I've been fiddling around with both Gebart's and Berger's 
windumps for about a month now and I've been learning quite a lot.

Previous limitations such as requiring the Nvidia vanilla binary, an 
overly cumbersome Xorg configuration, an inability to easily control the 
dumped Nvidia desktop, and a thirst for hosing your computer have been 
lifted.

The only thing that has been lost for the moment is matching the Nvidia 
desktop to the native resolution of the LVDS. GL on the Intel desktop is 
still not working.

What has been gained is nearly effortless use of VDPAU as a video output 
in mplayer2 and Flash. There have been two bonus surprises: NV17 Texture 
Video available on both desktops before windumping and the ability of 
Nouveau (using attached xorg.conf but changing to nouveau) to also windump.

The next steps are probably far more complicated since I know pretty 
much jack about the graphics stack. Above all else, windump needs to be 
redesigned but I'm curious to know whether it can be used if an 
appropriate xorg.conf is loaded by Bumblebee (the attached does allow 
Bumblebee to function properly).

Finally, I'd like to thank Fabio Giovagnini for sharing a nice dual-head 
xorg.conf to work with.

If you guys have any ideas or thoughts, feel free to share.

- Eric
