How to build GPU compute marketplace?

Question

Is it possible? Let's say Alice has 2 GPUs idle at the moment, Ben has 1 GPU, and Chris needs 3 GPUs for the next 12 hours. How to build such a system, and what problems there might occur? How to handle turning off one's machine? Does it even make sense to run training or inference on such (latency)?

More task specific compute pools (like Stable Horde) make lots of sense where applicable.
