As you know, lately using GPU for general processing gets more and more popular
You know, IE9 does something of it, a lot of other things do that, so, basically, future will be in GPGPUs, I suggest you to slowly began working on it, researching it and so on.
You can make FS products to be able to detect if system is acceptable for that, and/or make some kind of settings for that(e.g.. Do utilize GPU, or use this % of GPU and CPU so on, and so on).
This is kinda futuristic so far, but in few years most of resource demanding apps will be utilizing GPU.
Thanks for submitting your idea. I will check the viability of your idea with our Research.
