Yes, but once a browser ships ws/wss then we're stuck with that version of
the protocol.  If it starts to catch on, then browsers will need to
implement it for a very long time to come.  That's what happened with

By using webkit-ws/webkit-wss we're giving ourselves some wiggle-room until
we're sure we're happy with the protocol.  And I'm not convinced that we'll
know whether we're happy until we have some data from real-world use of
WebSockets.  (Which should start coming in soon after Chrome 4 ships.)
