OK, so if I understand correctly, third party tools like PrintAgent 
or PyKotIcon really are necessary to support the general case : ensure 
the username and password are checked locally on the CUPS server 
which manages physical printers, while being directly asked (over 
the network) to the remote end user, even if the end user has to hop 
over several CUPS servers to send a job to a physical printer ? 

Couldn't CUPS support such a (configurable) functionnality natively 
in the future ? 

Of course a cross-platform (preferably) client side app would be 
needed but I'm willing to contribute my own code which does just 
this for inclusion in CUPS if you ask
(working-but-soon-to-be-rewritten-for-over-a-year-now).
