Sedna's an interesting case. It ranges far beyond the Kuiper Belt in its 12,000 year orbit. While it doesn't quite extend as far as the conventionally defined inner regions of the Oort Cloud, I've read that some astronomers think the Oort Cloud's dimensions need to be adjusted to account for Sedna. So... If you're from the "OC" and you're just briefly (i.e., for a few centuries) slumming in the Kuiper Belt, I don't think the IAU is going to let you call yourself a planet.
