Bonjour Olivier,
You already have this possibility, as the NDX features digital inputs. You can then use it as a DAC for the Qobuz player running on your PC, Mac or even a SqueezeBox Touch or a Sonos.
This said, I guess the meaning of your question is different. In this case you might find this June 2013 blog post from Qobuz interesting (in french, but I guess it's OK for you):
http://blogs.qobuz.com/qobuzbl...-futurs-innovations/
(tl;dr: It lists the partners that are in the process of integrating the Qobuz API, Naim being listed among them.)
HTH
