Little work has been done so far on the SOAP binding. Certainly, 
your suggestions fit with the way I see the SOAP binding moving 
forward, i.e. a transport agnostic binding, the MEP being 
selected via the WebMethod feature, this feature appearing either 
at the binding or (binding-)operation level.

As far as fantasy is concerned (a unified HTTP-SOAP binding), 
this may set the bar too high.
