Hi Grant,
Intriguing solution, using a DHCP server effectively as a switch. Unfortunately you are correct that ROCK won’t run the DHCP server; it’s a dedicated OS for Roon Server only. Not sure what advantage you would get from ROCK, your current system seems to suit your needs. You could try a physical switch if you wanted to try it out.
Love the name change to ROCK btw. 
Hi Andy,
Thanks for the clarification, much appreciated. You’re right, there’s nothing wrong with my current setup. As the NUC is solely dedicated to Roon however, it would be nice to have the OS as lean & maintence free as possible.
I think I actually do have a spare gigabit switch laying around somewhere, so I can certainly give that a try. Not quite sure how the IP addressing would work though (in the absence of a DHCP server). Will ROCK allow me to set a static IP address on the LAN interface?
Congratulations on a fantastic product BTW. Very much looking forward to all the 1.3 goodness!
You could either re purpose an old router and use it’s DHCP server, or add a two or more port bridge (often sold as gaming adapters or wireless range extenders) and add internet connectivity. Often routers can be configured to work as bridges.
My accountabt and I both wish I could take some credit for Roon, but I’m just a volunteer moderator user (full price life member). It’s the devs vision and a mighty fine one it is.
ROCK has no access points open to users. You won’t be able to SSH in. It will update as required automagically.
So not sure where the LAN interface you refer to is. If on a physical switch or a bridge, dont see why not. If running on the NUC, no because no LAN interface is accessible under ROCK.
UPDATE: I’ve moved the contents of this post to a KB article that i plan to keep up to date:

What else do you want to know? Ask questions, I’ll update this list, and delete your question
Thank you @danny . This is the exact type of post we need as delays occur so we have an idea as to how to plan.
Press on.
Thank you, I now feel confident in buying a Nuc.
see my note at the end of the page… you might want to wait… we will give you notice so you have time to buy hardware before we release, and we have a surprise for you that may (or may not) be interesting…
Darn it! What can the surprise be? I already bought a NUC in anticipation of ROCK…
if I order before midnight it will be delivered tomorrow at 9.00/10.00 am. There’s a huge pile of NUCs 
Hi, a very stupid question… where I can download Roon Optimized Core Img ?
tnks so much
Not available yet, soon.

Dare I ask about a release date? I know it’s only been 16 days but that feels like a lifetime when waiting for something as exciting as this !
You can ask but the only answer you will get is it will be released when it is released.
Perhaps a brief update of status will be greatly appreciated by many of us since this topic had been mostly silent after the hint of a “surprise”.
Some had been waiting a bit more than 16 days 
I just hope ROCK doesn’t end up following the same development pattern as the 2nd generation Honda (Acura) NSX. … announced in 2007, on sale in 2016.
Well seeing as you won’t be asked to pay for Rock, that is unlikely. Remember this will be a gift horse…
Can’t agree there. We have paid for the horse. We are just waiting for delivery!
You did NOT buy Rock, you bought Roon.
