I am a developer and author with Lynda/Digital Tutorals/PluralSight. My latest work is a multiplayer server for unity that runs on NodeJs and I am building it up to have MMO support.
I also just got myself an Oculus Gear VR. I was thinking of making an MMO for VR. What are your thoughts? I would be able to produce this fairly quickly if there was enough support and with assets from the asset store.
Good idea? What would you like from it?
I would like to see you make some tutorials of your journey to make a VR MMO on Lynda. 
Now that would be very cool.
If I end up making a game, I will make a course about everything I learn 
But first I need to see if its in demand
Are you asking if the video would be in demand? Anything that has info on making an MMO will be in demand. You do not know how many “How do I make an MMO” requests we get here.
If you are asking whether people will buy your game, you are probably asking at the wrong place. Although I imagine there are many who would love a VR MMO. I have had people ask us to do that, but until your videos are out, I have to say no. 
Would you be able to get enough information packed into this tutorial that could literally step by step walk you through thousands of hours of work to make an MMO? That’s the only issue I see about this, MMO’s in my opinion at least are something you either know how to make or you don’t. Meaning you having already made networked games having experience, and unless you have that experience you will be lost outside of what is being shown to you in the videos, unless you’re just truly an exceptional learning. Now I mean would I personally be interested? No, not because I don’t think it’s interesting, but because I don’t want to target Networked games until I’m already established more than I am now. Servers ain’t cheap for a startup with 0 dollars lol. But do I think it could be in demand, yeah as Teila mentioned - MMO stuff is always in demand, and could potentially be a money machine as so many people learn how to code and think they an take on the world only to find out they can’t and must learn more. But just in my opinion - if you do decide to do it, make sure it stands out from the few free tutorials flying around out there.
Noo I was asking what features people would like to see in a MMO VR game
Well, why didn’t you say that? 
How about skill based rather than level based? There are so many level based MMO tutorials out there, very few skill based as far as I can see.
As for the VR, are they any out there at all? That should be enough to make your tutorials in demand.
