Just a quick question, since I can't seem to find a straightforward API to do it:  Is there a way to get a check our report on the disk usage for individual users? 

We're contemplating raising the user disk quota after having a few students report problems submitting assignments due to disk quota issues, but we'd like to get a sense of how big an issue this issue and how many users are getting close to filling their quotas.  Has anyone come up with a good way to check this?

Thanks!
