Still have to add to the documentation, and maybe clean up a small thing here and there.  ;)

> A WS Proxy primarily focuses on the consumption of an external WS endpoint (e.g. hosted on .NET, another external Java-based AS, LAMP) and re-publication of a WS endpoint via the ESB.  The ESB sits between the ultimate consumer/client (e.g. .NET WinForm application) and the ultimate producer (e.g. RoR-hosted WS).  The purpose of this intermediary is to provide an abstraction layer that solves the following problems:
>     * Provides for more loose coupling between the client & service, they are both completely unaware of each other
>     * The client no longer has a direct connection to the remote service's hostname/IP address
>     * The client will see modified WSDL that changes the inbound/outbound parameters.  At a minimum, the WSDL must be tweaked so that the client is pointed to the ESB's exposed endpoint instead of the original, now proxied endpoint. 
>     * A transformation of the SOAP envelope/body can be introduced via the ESB action chain both for the inbound request and outbound response
>     * Service versioning is possible since clients can connect to 2 or more proxy endpoints on the ESB, each with its own WSDL and/or XSDs and the ESB will handle the transformation & routing requirements to send the appropriate message to the appropriate endpoint and provide an ultimate response.
>     * Injection of things like WS-Security
>     * Complex context-based routing
> Current mechanisms of doing this are inappropriate or inadequate:
>     * SOAPClient is used to invoke external web services, not mirror them
>     * SOAPProducer only executes internally-deployed JBoss WS services.
>     * HttpRouter requires too much by-hand configuration
>     * EBWS strips out the SOAP Envelop and only passes along the body
> With a SOAPProxy action:
>     * it is both a producer and consumer of web services
>     * all that is required is a property pointing to the external wsdl
>     * wsdl can be automatically transformed via the optional wsdlTransform property
>     * multiple transports are automagically detected and handled (only http to be initially implemented, however, but jms in future?)
>     * if using http, any of the HttpRouter properties can also optionally be applied to as overrides
