When will it be possible to use IGP and discrete GPUs simultaneously?

I read articles about people chasing "holy-grails" in hardware, but what about something as simple as using an IGP and discrete graphics card simultaneously or in-conjunction with one another?

If you care about performance, you're probably using a GPU that's 10x faster than any IGP. So at best, adding the IGP can only speed things up 10%. And the communication overhead from dividing up the computation probably eats that 10%.
