Meteor.js is quite bigger platform than Angular or React things, cause it is including server side programming.
So If Onsen UI decided to integrate with Meteor.js, basic tutorial should be announced for Blaze.js that is default UI frame work in Meteor.js
I think blaze.js is just focussing on UI transaction, not a data flows,
so Onsen UI could be focussing on UI stuff as well.
Because Data is taken care by Meteor.js DDP protocols.
These seperate approach would be best practice for UI framework, I think.
BTW Isn’t there any big fan of Meteor.js here? lol~
