Additional note: Could I just use XMPP or that may not be sufficient given that the mobile device connectivity could be intermittent? I would love to get the community thoughts on this so I can make the right decision.

Thanks Ritesh

Have you looked at https://www.firebase.com/ (paid service)?

Thanks Walterbell. This is useful and I'd investigate further. Looks like Firebase is a combination of Pubnub and Push.
