node.js - Cross dekstop/mobile authentication in HTML5 game (Facebook, Google, Twitter with oauth) -

me , friend thinking of developing kickass html5 multiplayer game. our developer dream launch 1 codebase (as far it's possible) ios, android , desktop browser.

we're thinking creating whole game (client side) single page aplication in bb (managing views, api calls, canvas etc.). publishing on www server casual site or wrapping though phonegap publish on mobiles.

backend stack far includes:

node, express (game api), mongo, socketio passportjs extensions

frontend:

backbone marionette pixijs (for canvas rendering), maybe cocoonjs boosting phonegap (??? it's wrapper additional libs i've read)

how handle different authentication policies @ cross platform environment. google play, appstore distribution system, need login facebook, google+ or twitter on our own , remain away i.e phonegap-social works when publishing on mobile. right?

if go bb , spa, should not reload page, how show fb/g+/t authorization popup in front end , route params in background client app server when logged in?

what best practices create authentication universal, what's experience?
