At this point we do not have a plan that would allow for a positive out-of-process plugin experience on Mac OS X 10.5. We should only allow out-of-process plugins on Mac OS X 10.6 or higher. There are a lot of issues here, and I suspect Apple had a lot of the same problems we have run into (Safari does not support out-of-process plugins on 10.5). Topping the list is drawing performance - we don't have a way to provide any sort of accelerated drawing. We cannot accelerate Core Animation on 10.5 like we can on 10.6, and Core Animation support is generally buggier on 10.5. We also cannot accelerate Quickdraw, which is Flash's "fast path" on 10.5. Even if we were to try to implement Quickdraw/Carbon (we'd have to do both, a whole different can of worms), the result would be too slow. Chrome has tried this and the performance is bad enough that they trick Flash into using Core Graphics (slower than QD for Flash) by swapping direct/gpu wmodes out from web content.
