I have talked to a few folks who have done experiments with this approach, and the consensus so far is that it adds a lot of complexity, that the promises of hardware-independence from tools like OpenCLI are not truly being met, and that the performance boosts are not as big as one might hope/wish. So, currently shelved and waiting for a new era: I would say having a reliable GPU abstraction library for multi-vendor support is a bar which must be met before spending any serious effort on the work.
