Hi,

We do not support such a solution: our library is JavaScript only, the solution you suggest would imply to import a swf file in our own library.
On IE9 you should be able to get a HTTP streaming connection: excluding the client to server communication such connection is quite the same as a WebSocket connection; do you have a huge client to server traffic?

In any case I don't believe we're going to directly support the swf solution; On the other hand if you find a library that implements the correct protocol (RFC 6455) and exposes the correct WebSocket JavaScript interfaces (http://www.w3.org/TR/websockets/) on the browser our library will be able to detect it and use it.
