This could be possible,but the situation is as follows:

1. On client side you use XMLSocket.

2. The work to be done is on server side:
"To use the XMLSocket object, the server computer must run a daemon that 
understands the protocol used by the XMLSocket object. The protocol is 
as follows: ..."

So you need to write a xmlBlaster protocol plugin on server side which 
understands the
thingies send by XMLSocket and sends back bytes&bits as XMLSocket 
expects it.
