Ohh ok, that'd work with the recent MOTU ? Interesting, that makes the Ultralite AVB worth a closer look. Would that mean i could, like,
just attach an N-DAC 8 to the MOTU and see another 8 outputs in JACK ?
Sorry if i sound a bit naive but i have no experience with network audio
so far ...

Almost... before starting jack, maybe before plugging in the the ultralite's USB even, connect the ndac. Then, using the web app on the ultralite... uh, oh... Hmmm I guess that means you already need an AVB type switch :) but anyway, using the web app, set up the ultralite to accept the 8channel stream from the ndac which will make the utralite have more or show more inputs. Now connect the ultralite to the computer and the extra channels shoulld show.

Now I am not sure this is exactly right. The ultralite may show enough channels all the time (there is a limit BTW). However, from reading the manual, I get the idea that routing still must be performed and that ALSA (via USB) can't do that. You need to use the web interface which uses the same network port as the AVB network. So a minimal system is an ultralite only works as audio interface and the network needs to be connected to your computer. The next step to add one AVB endpoint requires an AVB hub as well. So that would be three boxes for a minimal remote box system. In my case, though I would love to experiment, it will remain on my todo list for a long time yet :)  My legacy PCI interface will have to do.
