email accuracy not checked when used with Login Toboggan

Hello drupalers,
I use Inline Registration and wanted to have the ability to check the email accuracy when registering a new user.
The only way to do that at the moment is by using Login Toboggan (see http://drupal.org/node/583152).

=> LT has the 2 emails fields display on the registration form.
But email addresses similarity is NOT checked, so the registration can be made even with 2 different email addresses (the first email address is the one recorded in the database).

Any solution here?
