Okay I'm going to answer my own questions here (found the
/usr/share/doc/smm/04.quotoas)

Group permission are cumulative for all users!
To give each user a quota you should create a template and then you can
"copy" quota information for each user from the template user.
i.e. 'foobar' has been setup with permissions, 'goobar' hasen't.  So...
'edquota -u -p foobar goobar'
will copy foobar's limit levels to goobar.

BTW quota blocks are 1K in size.

As for CPU load(from 04.quotas):
"Measurements have shown that the quota code uses a very small percentage of
the system cpu time consumed in writing a new block to disc."

Now new question: edquota can add quota for a user or group, but what
happens if the user is removed?  How do I remove the non-existent user's
information form the quota file(s)?  It seems to me that on large user
systems these files could accumulate a lot of dead space.
