I just wanted to propose this, but you already did.
In Romania there's also a payment processor (netopia mobilpay) that accepts Bitcoin. And the only way to encourage this trend to rise is to use this payment method whenever possible.
I just made my first purchase directly with Bitcoin last week. It didn't went as smoothly as with card, but I think that both parts will learn and improve the system. It's a good start however and it's the way to go.
