that is precisely why I did it this way.

generally I do it by size. so a user can upload say 5 gigs worth of files and the upload script
will query the database for a sum of filesizes of all of that users files to see it they still
have space.  This is where I am really exited about the prospect of doing this in mod_perl. 
in the past, if you were uploading a 1 gig file but did not have space on your account you
would not get an error until the entire file is uploaded.  I am thinking with the way mod_perl
works I can query the db for that user  before the entire request (upload) is made and throw
an error immediately  (though I could be wrong)

I guess another thought I need is not only the size of files but the actual number of files...I
suppose there is a choking point when there are just too many files in one directory.
