 Mark,
 I'm only maybe starting to get far glimpses of what the
non-tunnelists may mean by their non-tunneling approach, so I
meant a "SOAP Application use case", not "other possible
bindings' equivalent use cases".
 I think that from non-tunnelists' POV the binding usecases could 
be sufficient, and if the group shares this POV, it will discuss 
your proposal. I'll just stay skeptic about this approach 
intermixing the layers for a while.
 Best regards,

                   Jacek Kopecky
