Invoice and regular debit authorization support

Hi Paolo, hi GD-Team,
I’ve 2 items in question:

1) I know you’re working already very hard on an invoice plugin. Do you have already a rough timeline when this plugin can be moved out of the beta status and become productive?
Background: In Germany it is mandatory to send invoices. Without this plugin the whole GD framework is questionable to me.

2) In Germany there is another way to get regular money from the customers. If the customer is agreeing to debit authorization the merchant can transfer money on a monthly base.
Actually during check out there must should be a form where the customer can enter bank details. After successful verification the merchant can move the listing from draft to published.
Is there any possibility to support this for regular payments?
