WCF and WS-Adressiong   

I'm trying to access a WCF service via an intermediary that accepts and 
forwards the request.  This works fine using the basic http binding, but 
using WsHttpBinding turns on WS-Addressing.  Since the client is sending to 
the intermediary, the wsa:To element contains the intermediary's URL.  The 
intermediary forwards the message verbatim to the target service, which 
rejects it because was:To doesn't match its own URL.  Back in WSE 3.0, you 
could work around this by placing the [SoapActor] .attribute on the target 
service, but I don't know if there's a WCF equivalent.  It is not an option 
to make the intermediary understand WS-Addressing.

So, is it possible to do any of the following?

1. Cause the client not to add WS-Addressing headers
2. Cause the service not to process the WS-Addressing headers
3. Cause the service to accept an alternate wsa:To address
4. Cause the client to send a different wsa:To address

By the way, if there's a resource that explains this stuff, feel free to 
answer by pointing to it.  I'm finding WCF distressingly opaque compared to 
WSE, and something that could alleviate that would be most welcome.
