Only if you use a backend that supports per-user quota, like FTP. But  
that could cause problems.

Don't use linked attachments. Or configure different VFS backends for  
the different VFS usages in Horde applications.

It's a feature. It's your choice if you want to provide this to the  
users. It's also your choice if you store them in the database or  
anywhere at all.

There are a lot of different usages for VFS, and each place takes care  
of garbage collection or deleting files regularly fro VFS if it makes  
sense.
