I'm wondering if there are any good examples on making a custom node to handle subscribing to a realtime api channel. What happens is this:

- first you send a post request with your user/pass authentication to a handshake channel
- the api server responds with a unique client ID
- you then can subscribe to different long-polling channels with a post request using this client id
- the server will hold the request until information is available and the client then immediately sends a re-request
- in case of server timeouts the client connects again and starts over

The goal of my node is to simplify this workflow into a node that takes the channel you want to sub to and your user/pass and then will sit there and sub to the long-polling channel. Are there any good examples of a handshake -\> sub node already? Thanks
