Bing/Google Maps API - How to disable parts of the map

I am doing some research for what map to use for a coming project.
The main requirement is to be able to lock a map, and the ability to
disable parts of the map.
Think about a special purpose map for Europe. Then I would like to bring
in Bing or Google Maps, and disable and gray out the non-european
countries. A click on those grayed out areas should do nothing, for all of
the world.
I also want to disable the possibility to zoom, and move the map around
once a zoom level has been applied.
So, is it possible to disable large portions of the map? Is it possible to
add layers for the borders for each country, that is clickable?
Bing or Google Maps? More developer featured one? Bing looks so much nicer
with the birds eye, much easier to read out the map really.
Thanks!
