Just confirming Just.Jake's words, he did indeed send it. I've been swamped this week, so I've not been able to test it yet, or prep for a posting here. :/ Sorry.

Kinda. As of Leopard, Quartz Composer includes a "Screen Saver" template, which provides a "_protocolInput_ScreenImage" --- which takes a screenshot just prior to launching the screensaver, and feeds it into the composition. I marked it "Done" because that fulfilled what I wanted for "screen capture" functionality.
Whoops, and re-reading the original post, I guess this is done.
I find it irritating that, to my memory, if you load any .qtz with that input into the Apple Screensaver library, and activate it as a screensaver when you have password implemented, all you see is "black". I think that is why Fenetres uses Cocoa to get the screengrab...my memory could be failing me on that.
I also think it sucks that the "protocol" screen grab can't be set to grab specific windows or coordinates at worst. The thing that would like is to do live/video screen grab of a small space in Processing, Nodebox, etc., and route it into QC with the appropriate buffer to keep the computer from blowing up.
If it was possible to set it to grab a specific window... you could set up Processing in a different position in Spaces from QC... ah, dreams.

Yes, that could be quite cool.. Using CGWindow, as Just.Jake and cwright discussed above, it might even be possible. Also Apple provides http://developer.apple.com/samplecode/SonOfGrab/ which may be helpful in implementation.
I've edited this featurerequest and marked it 'not done'.
Check out Fenetres Volantes at http://objective-cocoa.org/fenetresvolantes/en/index_en.html
Stuff like that should now be easy to do via the CGWindow API.
I've got this working, using the CGWindow API. I sent it to cwright.

I checked out Fenetres a long time ago...
But, is there away to actually do the screen grab within QC? This one is marked as done.... is there something I missed here!?

What other uses do you have in mind?
