Yes, if you run through the memorized list once a day, in a few weeks you can free up that parrticular palace for other work and keep the memory --- you've memorized by rote.
As for scale, many memory workers use a linked list as well as the memory-palace array. Associate each item with the previous item, and you don't need 10,000 room palaces; just someplace to put the head of the list. That's how I memorize decks of cards: http://blog.diiq.org/post/3366119815/what-are-the-step-by-st...
Thanks for sharing this. I'm more prone to associative stuff, only that they require more work. Will have to move some lessons I'm memorising to a linked list to free space ;)

An excellent resource is Lorrayne and Lucas' The Memory Book:http://www.amazon.com/gp/aw/d/0345410025/ref=redir_mdp_mobil... , which has been lifechanging for me.
