Hi Matt,
Right now, one of our devs is most of the way through an unannounced control. Once he finishes that, he will probably start working on this sort of thing along with some other related controls like masked editors in preparation for yet another unannounced product. :)
But in regards to your request, I've seen calendars done two way. With the up/down buttons and with a popup that shows when you click the year and a number of years before and after available like a menu. Which sort do you (and anyone else reading this) prefer?
