I looked about for how to do something like this a while back. I was told that(and couldnt exactly find a way myself; although Im not much of a scripter) there is apparently no way to ad hoc remember a previous random location without using mark and recall. That, or no one was clever enough to do it. If you find a way to move the player to one cell while remembering the previous cell and coords without use of mark and recall, I would be very interested in it.
Take a look at the teleportation ring in Andy's http://planetelderscrolls.gamespy.com/View.php?view=mods.detail&id=2156. When you equip the ring it takes you the Lookout and I think unequipping it took you back where you were before.
