What are some of the positive and negative comparisons between these for develop realtime web apps? I use SocketStream now.
There is some documentation on integrating SocketStream with EveryAuth here: https://github.com/socketstream/socketstream/blob/master/doc/guide/en/authentication.md
There is also a tutorial here (in Japanese): http://new.takyam.com/entry/2013/01/01/SocketStreamにeveryauthでTwitterログインさせる
A couple of months ago, I did attempt to integrate passport-js into SocketStream, but I need to do some more work on that, and that will take time. I will let you know how I progress.
