Adapt websocket-feature to other server frameworks

[DataWorm]

I read about the websocket implementation to sync data between server and clients. As far as I remember it was mentioned that a specific framework was used to create that websocket server. Is there already a more general interface to adapt it to another framework? Like integrating that websocket stuff into jetty, netty or any other framework? Of course I could just open a second websocket server and forward it to the greycat's websocket server but I was just curious if there is already a more elegant solution. It isn't an urgent feature for me anyway.

Thx for your time!
