I realise this is rather eleventh hour, but it would be great if D7 could include support for SSL connections to MySQL, and other database servers that support SSL connections.
In D6 this can be achieved by changing the mysql_connect call in includes/database.mysql.inc to:
$connection = @mysql_connect($url['host'], $url['user'], $url['pass'], TRUE, MYSQL_CLIENT_SSL);
With more people using servers that they don't have physical control over this would be a great thing to have support for out of the box. I haven't looked at the D7 database code, but realise it has undergone significant changes from D6. If I'm not the only one with interest in SSL support I would be happy to help with the necessary changes.
