[jdev] Help choosing the right technology

[Abhinav Singh]

Most of the questions are already answered and I believe you can achieve all that you want with XMPP alone.

Coming back to the question "Help choosing the right technology":
if machine to machine communication and light weight messaging transport 
(especially since you are on mobile) are your top priority, consider investing some time in MQTT. 

Drawback: Compared to XMPP you won't find enough open source implementations for MQTT, 
(however the specifications are dead-simple and in no time you can pull off your own client/server implementations)
Also, if you are looking to take full advantage of roster/presence/messaging that comes with XMPP, 
MQTT might not be the right choice for you.
