mmmh... i was thinking about porting the Yahoo maps stuff as Mojo to the Mojocafe but then thought: nah, people won`t need that as Mojo.
So the question is: what i can offer you quickly is a solution where you, for example at http://www.mojocafe.net/maps, will be able to zoom and pan the map, and also change between the three standard views (hybrid, street, satelite) - would that be enough for you?
