I'm new to the remoting and it's getting late and I'm getting tired. I'm 
trying to figure out what interfaces I need to use in order to intercept 
messages at the various spots and how much is dependant on the order of 
sinkproviders in the app.config file.
Specifically I want to know which interfaces I should usee to:
1. Intercept messages on the client before they are serialized and sent to 
the server
2. Intercept client request messages on the server after deserialization and 
before being passed to the business logic of the app.
3. Intercept client response messages after they are passed back from the 
business logic but prior to them being serialized for transmit to the client.

Any help would be greatly appreciated.
