Quite - even Windows explorer doesn't explode all the subdirectories at 
once when you open it. In essence the same kind of approach is required 
- checking access rights to a list of siblings and a when the user opens 
up another branch another list of siblings is checked. On the other hand 
implementing a more efficient caching system that uses the database 
sounds like an interesting idea. If the caching lasts any significant 
length of time it would be necessary to invalidate chunks of it when 
permission changes are made.
