At this moment, my QuotaFolder only limits the total number of objects,
their total size (sorta) and the maximum size of individual objects.

Future plans are to restrict installable types in general (i.e. restrict
people from installing LocalFS, etc), or to limit the number of these
objects.

If you want to code something like this yourself, QuotaFolder may be a good
startingpoint. I will release the product later this week, but people who
want a preview now should email me and I'll send the current version (which
basically lacks some documentation)
