And if you have 5-10 users which should be under quota , you need 5-10
different mount points. From my humble opinion that's an absolutely crazy 
solution and nobody will ever do that.

Yes, I completely agree that it's up to the comunity to decide whether 
the feature is worth the complexity of its development, but I don't agree 
that's a duplication of existing functionality. IMHO.
