With all assumptions in place... that there is at least one being that we would describe as a deity, this is actually the model that I prefer.
A god would certainly be able to subdivide its consciousness, much in the same way that people are able to have multiple personalities. If a god had a desire to experience its creations, then this would most certainly be its method of doing so. Each person's ego would be the 'key' to the experiences, limited in knowledge and functionality. The reason why I put the Douglas Adams quote above, is that if any ego attains a full knowledge of its infinite perspective, the universe instantly disappears (since the god can no longer experience things from a perspective of ignorance and impotence) and a new, more complex one would instantly spring into existence to replace it (so that the god can continue to experience everything). There's also a theory which states that this has already happened.
