in openser, module functions may return more than true or false - there
is the return code variable "$?" or "$retcode" which may be tested.
usrloc may return -1 for not found at all and -2 for found but not
matching method:
....
lookup(location);
switch($?) {
case -1:
sl_send_reply(404);
break;
case -2:
sl_send_reply(405);
break;
}
t_relay();
.....

that was just one application before we can also use method information
for contact selection.

yes, but there are some complications. if i do lookup for a particular
method and that method is not supported by any contact, but contact(s)
supporting other methods do exist, then script should return 405 instead
of 480. this means that binary result from lookup (0 or -1) is not
anymore enough.

yes.
