Asynchronous work - what are our options?

Hi,

I was hoping to do some asynchronous work, though I do not believe this is possible (due to the limitations of javascript). The work I need to do is not an http request, it's computing some AI stuff for a game. If I understand correctly:

1. RPC is reserved only for http communication. There's no way to just launch an asynchronous task where my own clientside code is run in the async handler.
2. There are now things called "web workers" as part of html5, but GWT doesn't have wrappers for them yet?

Thanks
