Larry's initial thoughts: wait to see how many people request it as a feature. Frankly we haven't had many support requests from people who can't remember their own Email address.
I did a mock password recovery test, in which it took about 2 and a half days to have a link sent to change my password. If it may make the process for account recovery possible:
--Click on "forgot password"
--Be prompted with a small list of questions you yourself set in.
--After answering the questions, forcibly remove password and be given a randomized, programmed password. Afterwards, change the password, if you wish.
With this, account recovery would literally take ~10 minutes.
