Will nodeJS and socket.io be able to handle few hundreds of thousands of concurrent users in a chat app?

I need to build a basic and simple chat app (register, login, join room, send messages in rooms, send PMs to other users) that will serve approx few tens of thousands of people right from launch day with the possibility that it'll grow deep into the hundreds of thousands of users, and I need to know if nodeJS (which is a single instance app or whatever you call it) along with socket.io can handle this much data and users at the same time without hiccups, if it can't by itself then how can I make it work with maybe some library that will allow me to upload the same server app on multiple instances but guide them all to behave like a single instance (just throwing ideas here.. LOL)Thanks in advance :)
