Document that bakery doesn't work with different top level domains

Hi,

I've been struggling with http://www.drupal.org/project/sso and wondering if Bakery might be a better alternative.

This is to work with the domain.module http://www.drupal.org/project/domain

What I need to know please is, will Bakery work with several top-level domains and not just sub.domains?

master database (mainsite.com, anothersite2.com, anothersite3.com, etc):

$db_prefix = array(
     'default'        => '',
     'users'        => 'controller_database',
     'sessions'       => 'controller_database',
     'authmap'          => 'controller_database'
   );

slave database (login.mainsite.com)

$db_prefix = 'controller_database';

I've read all installation and faq files, but do not see if it is possible to be logged into several top-level domains.

Looking forward to any reply, and thank you.
