status label now has service status instead of username; service [un]lock observer notifications are gone; don't error when async methods don't call done() - consider them methods with no return value; don't require passing null into login() to cause the identity to look up the password in the pw mgr; make some wrapper 'method generators' to make lock handling and observer notification simpler
