[Zope] Limiting folder space

I want to use Zope to offer registered visitors to my site a little free webspace on the site. Since I use hosting service that restricts and charges me for space, I would like to restrict the size that their zope folders can consume. Hence: Is there any simple way of limiting the amount of space that a folder is allowed to consume including its subfolders? Alternatively, is there anyway of checking how much space a folder with subfolders consumes? Regards, Brendon ------------------ 70South: the No.1 source for Antarcticles.
