Thanks for the support and I will try to be more specific. 

Assumptions:
1) basic layered architecture: transport, application
	(Pick what ever words work for you, these are the labels I
	am most comfortable with.)
2) intermediaries may be part of a layer or may represent their a
	new one---I am not debating that at this time.

3) an interesting and significant part of an architecture is to
	+ describe the roles and responsibilities for the layers
	+ describe how they interact

Proposed work items:

1) create strawman for layers (or equivalent)
2) place intermediaries in one (or more) locations in the arch
3) describe reliability as it relates the layers
4) identify roles and responsibilities relative to the layers.
etc.

Clearly, there will be several models of what reliability is
and how to achieve it. SOAP, REST and all the other perspectives
will need to be considered. But at least when we are done it will
be more constructive than simply agreeing to disagree.

Good idea.

Can you elaborate on what you mean by that?  I don't understand.
