There have been some major changes since hybi-03 including the client side masking to address the security issue with poorly behaving intermediaries.
So I think HyBi-06 (or higher if a new draft is release in the meantime) should be the target: http://tools.ietf.org/html/draft-ietf-hybi-thewebsocketprotocol-06.
Yuta, if you agree, perhaps you could edit the subject to reflect that?
As I discussed with Alexey off-line at the WebKit contributors meeting, I would like to implement the new protocol next to the current one, and make them switchable dynamically (through Settings class).
I will post necessary changes.

I see the current code support version 8. The hopefully final spec released today is version 13. The differences are minor. Do you have any plans to upgrade to 13?
Chromium is going to update our WebSocket to 13 on the next release (Chromium 16). Yuta is preparing patch for WebKit now.
FYI, Chromium dev channel is now using version 13.
