Zoomable Google maps?

Anyone done the work to use the Google DragZoomControl (http://
googlemapsapi.blogspot.com/2007/06/dragzoomcontrol-v10-easier-
zooming_06.html) with ym4r? Would certainly make my life easier if
someone could point me in the right direction, since my client has
their heart set on this UI and I haven't a clue...
