Hi!
I am big fan of Meteor (since 0.9 version). Also, I integrated Vue with Meteor few times. For that purpose, I created very simple entrypoint for my next Vue + Meteor project. Personally I used it three times, but just today I decided to make it public and share it with you.
Does it support realtime updates? And if Yes, how do you subscribe and handle subscriptions?!
No, I did not introduce sub & pub integration yet. I will update the repo and let you know, thanks for the feedback! 
Are you interested in joining up on the effort of making vue integration easy? I’ve build a similar boilerplate and don’t want to double do the work. 
I have some boilerplates here which I’ve shared on the forum aswell:
Also I’m working on the guide and the tutorials, but unfortunatly I did not get the tutorials to run locally. I could use some help on that.
Just as a status update, i’m awaiting some pull requests to update the Meteor guide for vue ssr:

2 other requested topics were:
At the beginning I decided to write few words about “How to integrate Vue with Meteor’s realtime data layer”.
Just let me know if the direction is good.
