Follow up --- I have just been told that the
issue will be resolved over the weekend -- there apparently is some
issue being dealt with first.
I should have the 44 files in the inbucket on Monday.

Yes, the builtin accounting facilities do most of the stuff you
are interested in. Just add 'accounting_enable="YES"' in your
/etc/rc.conf, run '/etc/rc.d/accounting start' and use sa to
examine the output. I believe the per-user accounting will fit
the bill nicely. You did not mention jails, right?
The networking part perhaps can be a firewall's job, though
I don't know if the per-user IP traffic rules work properly.
There were some problems regarding this ages ago...
The builtin printing stuff I believe is for use with the
ancient printing tools and I know nothing about CUPS...
Hey, these are pretty old stuff you are looking for or perhaps
this email was stuck in the mail server's queue for 25 years;)
