This is probably a major project to tackle, but WebSockets are becoming a pretty common protocol. It's a totally different paradigm from other supported HTTP protocols, so I know that it would be difficult to integrate into SoapUI. The ability to open a connection, do the initial handshake, and send messages back and forth would be a good start. Ideally, I would like to be able to create a test case that can have an open webSocket connection and test steps to send/receive messages over that connection. It would also be nice to eventually have some load testing, duplex messages, mocks, and recording. Basically, similar support to what exists for SOAP and REST.
