Do you mean something like this:

%{name}-%{version}-%{release}.%{disttag}.%{arch}.rpm

.. where %{disttag} is _not_ an overloaded part of the "Release:" but 
rather a distinct entity derived from build environment - a bit like 
%{arch} perhaps with a tag to hard wire it in the spec if required, say 
"DistTag: any" for agnostic (I'm creating a new RPM tag in this example 
rather than changing the semantics of "Distribution:").

This would relate well  to my previous suggestion where %{disttag} would 
not be evaluated as part of the release on version comparisons but 
rather prior to the epoch: %{disttag}:%{epoch}:%{version}-%{release} 
(hmm, maybe after the epoch would be better?).
