If it's trivial to determine who is a "science" user, you could add a check
to the prefs.php file.  Something like:

$locked = true;
if (is_science_user()) {
    $locked = false;
$_prefs['from_addr'] = array(
    'value' => '',
    'locked' => $locked,
    'shared' => true,
    'type' => 'text',
    'desc' =>  _("Your From: address:")
