At the moment Bodington doesn't support account creation with an email 
address so we create all our accounts through a user import feed.

The plan is to allow people to create groups through be give them a 
specific part of the group namespace.

With disk space being so cheap I don't think it is too much of a 
problem. What makes storage much more expensive is good backups and 
management.

I much prefer the quota model that a site such as flickr has where you 
have a quota per month rather than an overall quota as this doesn't 
penalise the regular users and in fact encourages it.

1Tb of RAID 5 array is so cheap now do you need to worry?

No the exact opposite. No quotas will be against users. All quotas will 
be against parts of the tree and it just depends who manages the files 
at the part of the tree as to who gets to fill the quota.
