The momentary exposure in memory was the downfall of Lavabit. It is actually trivial to capture passwords submitted to servers during the momentary exposure. For example, when you login to a Drupal or Wordpress site over HTTPS, the POST gets submitted to a particular form - which is just a PHP file on the server, trivially editable. The password exists as one of the submitted form variables, which PHP then passes to bcrypt (or whatever).
