And I suppose you think that users will be sincere enough to mark files
as elastic? I, for one, already said that I absolutely would *not* mark
a single file as elastic. If I'm using 110 MB and you need an
additional 10 MB for storage, you won't be getting it from me because I
don't want to come in some morning to find that a file has disappeared.

The system that you're asking for is a system without quotas. Think
about what you're saying.

Controlled how? Who is anybody to inform me of what files I need/don't
need?
