I think the preferred context local structure might be better than the page vars (or my original idea). Only two things with mg have really "clicked" for me - the mg.xml/controller combos and having the page as much "presentation only" as possible. I hate to start doing things that feel like cheating already. I'm having enough trouble with the other stuff as it is.
Thank you!
