Still no (real) answer to this ?

Is this because the solution is in CUPS' documentation ?

Or is this because CUPS lacks the functionnality to ensure users
really are who they claim they are ? 

Cedric if you can't do this with CUPS (I really don't know), since 
you are using PyKota you can use its PyKotIcon add-on to do what you 
want. The sample pykota.conf configuration file contains several 
examples. You can also use PrintAgent it seems, which offer similar 
functionnalities, although less generic if I understand correctly.
