How about this:

Quota's can calculate usage by dividing the disk file by the
user count. A 500 MB file can be shared by 5 people who each
"pay" 100 MB.

(unfortunately this requires quota to read directories. I don't
know if quota has to do this already, does it just go through
owners of inodes (and is that possible in a userspace program)?
I really don't know quota that well.)

Then quota calculates for each user:

cost per user = total file size * (1 / # of users hard linking the file)
