Found a socket.io Library for Titanium Mobile.
socket.io Library is originally included in Node.JS, and someone brilliant migrated into Titanium Mobile.
And, currently there is no nowJS implementation for Titanium Mobile. But I investigated nowJS source code it used socket.io, and *maybe* it is possible to migrate into Titanium mobile as well. However, this is not impossible, because Kosso had made it, but just didn’t open source yet.
