FYI-

   KnowNow uses HTTP as a asynchronous transport.  Our event router uses 
async publish/subscribe semantics and speaks HTTP (natively, not as a 
bolt-on feature).  We recently wrote an RPC services-oriented layer on 
top of the pub/sub layer which can be both synchronous or async (using a 
callback).  It doesn't do SOAP encodings, though SOAP support is a 
natural next step which we're working on.  The lightweight service works 
in Java and JavaScript (yes, you can implement your server side in a 
browser if you are so inclined):

	http://cvs.developer.knownow.com/index.cgi/Libraries/JavaScript/JSService/

   The JavaScript version doesn't support writing synchronous clients, 
because JavaScript doesn't let you block on the reply.  Here's the 
sample client code in Java:
