Instant SEPA payments

Is there a list of banks which support it? What is the timeframe until all sepa banks support it (if there is any)?

EDIT: Ah after checking the link. Seems most banks support is very soon. Just Germany is a year delayed. But seems the list is not containing all SEPA countries and in some countries there are just a few banks.

But as soon it starts I will add a new payment method for it. Users need to know if their bank supports it or not.
