A couple of days ago I read somewhere that the javascript UI can send requests with SOAP and accept request back with a different protocol. This is because parsing the soap XML isn't really fast.

The problem is that I don't remember anymore what the protocol was and where I read about it. So can anyone help me finding the name and the link to this protocol.

I have a second question. Could it be possible to implement a communication layer that uses XML-RPC instead of SOAP. Offcourse without changing other parts of the library. I think this is possible, but what do you think?
