" I doubt the Saudi populace would look favorably upon a Shi'ite coup."

You are correct on the Sunni-Shi'ite conflict, but think Muslim Brotherhood as most of the populace in SA is not of a native tribe, but rather imported workers. Iran will over look sectarianism in the beginning to get the Caliphate established.

...most of the populace in SA is not of a native tribe, but rather imported workers.

Most of the imported workers in SA, though, are Palestinians or Pakistanis -- thus Sunni.

Your assertion that Iranis would be willing to support a Sunni coup, though, is probably correct.
