It cannot be done.
My Oblivion is trapped in the Xbox 360. Only my Morrowind is liberated to enjoy the bounties of the intertubes.
A shame. I had such dreams for Sheogorath's realm... Tea trees. Rivers of Tea. Simple quests to water plants with Tea. Tea rain. "Would you like some tea, Champion? WELL YOU CAN'T HAVE ANY. THIS PLANT WANTS IT MORE."
