One of the first things that comes to mind is issues with getting
avatars from gravatar.  As long as you can hash the email with md5,
don't care about ever seeing the email address again and write a new
get_avatar function (you can do that since get_avatar is in
pluggable.php) to not try and md5 the email address you would be ok.

This may not be the only problem.  Just one of the first that popped
into my head.
