Run Blender in the cloud? How and Where?

I would like to run Blender in the cloud, so I or others can access it from everywhere, from less powerful devices. Ideally the cloud-server would provide superior performance, and several people could use several Blender instances at the same time.

Many thanks for any help.

Spoon.net has Blender, but I’ve never used it before so I don’t know how good or bad it is.
