This is a great idea. I’m an enthusiastic Roon user since 1,5 years (lifetime membership) and bought a Vero a few weeks ago. Until now i haven’t thought about this playback possibility. For now i’m streaming to an Apple TV in my living room, which is connected to a Pioneer AV Receiver. But Apple TV is limited to 48 kHz and doesn’t support RAAT. Therefore it would be great, if the Vero could be used as Roon Bridge.
Now the good news. I’m listening to a Prince album (192 kHz, 24 bit) on my Vero streamed by Roon, while writing this lines 
It’s very easy to get Roon Bridge running on the Vero. I’ve downloaded “Roon Bridge (armv7hf)” in the section “Packages for manual installations” from the page below and extracted it on the Vero. “check.sh” stated surprisingly, that everything is ok and i didn’t have to install any additional packages. After running “start.sh”, the Vero showed up in the Roon Audio Setup and could be used as playback device.
Update:
Btw. just found and installed this Roon Addon for Kodi:
Now my Vero shows this nice Roon Fullscreen OSD:
