I've been checking out some of the latest multiplayer engines in HTML all supporting multi-user games (Very nice) - I believe all these engines use Web Sockets for communication.
That’s why we’ve decided to disable support for WebSocket in Firefox 4, starting with beta 8 due to a protocol-level security issue. Beta 7 of Firefox has support for the -76 version of the protocol, the same version that’s included with Chrome and Safari. Beta 8 of Firefox 4 will remove that support. Anne van Kesteren of Opera also announced that Opera are dropping Websocket support. We are confident that other browser developers will follow.

I've just come accross the above, so no sockets in Firefox 4 or Opera.... thats big. Is anyone aware of an alternate or is it Chrome or do we need to just sit and wait for the next release of the major browsers.
More info : Rocket Engine appears to work with all browsers including IE8 (http://rocketpack.fi/engine/) what will it be using as a method of communication?
