If flash can call native code, then I suspect yes. If not, definitely no. However, Flash is not GPU accelerated for anything other than displaying video (to my knowledge, basic rendering still happens on the CPU, and then is *presented and scaled* on the GPU. This means Flash is, for now, a poor choice for integration, as you (most likely) do not have any options to hook into its drawing context.
I could be wrong, as I don’t follow flash development much (at all). You might be better off writing a plugin for a WebKit based browser and pulling the info off of a view, similar to what CoGe Webkit does. Its still, for all intents and purposes, going to be sub-optimal I suspect.
