Err, sorry I read your message quickly and didn't see the subject, which 
would have told me you *did* see the osgscreencapture example! *sheepish 

I'll let others answer your question then, but I suspect using PBOs 
instead of glReadPixels will be significantly faster even if you can't 
multithread it (which you may be able to do, not sure).

Sorry for the confusion...
