There is a new Dante feature to provide routing locks with a pin code, this dependent on the manufactures updated their Dante cards, is it planned to update the Nion Dante cards in the near future?

Is it possible to upgrade/convert a NION (N3 or N6 in my case) to Dante via a card swap?

We have upgraded 4 N6 units in our theatre to Dante from Cobranet. Relatively easy.
