Cross Origin Resource Sharing lets servers support cross-origin Javascript. It is supported by the latest browsers (although IE support is... different), and involves sending CORS headers in responses.

Adding this enables Javascript code running in a browser to connect with any bitcoin/bitcoind that allows RPC connections from the browser's IP address and has the right rpc username/password.
CORS (cross origin resource sharing) patch from tcatm d07e519564

I think this needs to be explicitly allowed from the bitcoin client side, otherwise any website could start quietly bruteforcing the username/password out of a client.

Lets continue this discussion on the forums: http://www.bitcoin.org/smf/index.php?topic=2672.0

Not enough support for this right now... and there are SSL issues, too...
