[SR-Users] Advice on taking the best path to build a Presence & IM server

[José Seabra]

Hi Olle,

Thank you for your feedback about this subject, was really important to me
receive this in order to  follow the correct path.

Once that WebRTC is growing fast i also see some solutions based on xmpp
through websockets and others using a custom implementation based on
websockts and json.

I will continue my investigation to reach the correct solution to follow :)

Once again, thank you.
Regards
José Seabra
