Chrome Web Inspector Web Socket Debugging

Question

I can use the Network tab in the Google Chrome Web Inspector to debug the network traffic (AJAX requests, etc.). I can check what data is transferred easily. But Websocket connections only show as

Request URL:ws://localhost/...
Request Method:GET
Status Code:101 Switching Protocols
...

and I can't see the transferred data. Is there any build in feature in Google Chrome to inspect the transferred data? Or do I need to use Wireshark?

PS: I'm using the latest stable version (16.0.912.75). If a newer version (beta/dev) has this features, it would be nice.
