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.
