If v$sql gets populated before any records are actually processed (I imagine it is, but a quick test will verify) & the sql_id in v$session also gets populated after the query has been parsed but before any rows are processed you might be able to do it in a before update trigger that throws an exception. You'll need sys_context('USERENV','SID') to join with the v$ tables.

To be honest, you'd be better off using a cluebat on the devs :)
