The Trello team loves WebSockets for push, and we did all of our initial prototyping and a lot of the first version doing RPC over the socket for writes and gets. However, now that we're supporting a REST API for other services to integrate with, we're moving everything other than pushing updates over to that so that we only have to support one API as we grow Trello's feature set. If we decide to go back to making requests over the socket, my best guess is we'll use the REST semantics and just send method, URI, and args in a WebSocket message and expect a response.
