Hi,
Here are few questions:
- Groups: are these pre-defined groups, private groups, invite only groups?
- Do you need registration / verification, my account / standard pass features?
- Do you need back end to view users, chats?
- Do you want non-websocket browser support or pure web socket implementation (modern browsers) be enough?
On use of node.js, have you considered using go lang for the server? We can work both on node.js as well as go lang. We believe best performance could be received by using go lang servers (native code, no callback hell, stricter typechecking etc).
thanks,
Nirandas
