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...
