For similar objects, yes. But you won't easily find something similar. The 
cache doesn't consider a big area, only about the size of the aircraft AFAIK. 
Nimitz, for example, has 2071 faces (Only a bit more than twice as much as the
beacon! :-) But if you fly over it, only a few hundred vertices end up in the 
ground cache at the same time. Because of the small size of a beacon, all the
950 went into the cache in one go.

In less verbosity: this technique does only make sense for objects with high 
*density*, not high face *number*.

I could be wrong, of course ...
