Julian,

It doesn't follow from above that HTTP must have bindings as
they are specified in the binding document (and GULP).  One can
imagine a number of scenarios where there are multiple
URIs for a resource that have quite different semantics and
behavior.

In fact, it's easy to imagine a different binding draft
that specifies, for instance, soft links.  This binding
draft would be perfectly consistent with both HTTP and
WebDAV, but would behave very differently from the
current draft.  In fact, implementations which are built
directly on top of unix file systems might prefer that
draft to the current draft.  Are there good reasons to
prevent other binding models by forcing the binding
model of the current bind draft into WebDAV?

Especially given our lack of experience with deploying
bindings, I'd prefer WebDAV to be agnostic for the time
being.  Let's face it, file systems find a need to
support different binding models, so it's plausible
that WebDAV might find this need as well.
