I neglected to forward the answer on this to the MathGroup until now. Lo siento.

This would be something like simple DisplayFormulaNumbered cells in a
notebook versus

eqns={a==b+c+d+e,a+b==c+d+e,a+b+c==d+e,a+b+c+d==e};
Grid[List/@eqns,Alignment->"\[Equal]"]

The problem is that the front end will only increase an automatic
numbering object once per notebook-level cell and that it can only
align elements in the same cell.

Thus, there seems to be no way to have automatic numbering (and, say,
cross referencing) of equations that are aligned.

Chris,

The response I have gotten indicate that this sort of alignment is not
yet possible.  I am told that the closest implementation is in Publicon,
but that it is unlikely to work outside of Publicon.

This is known and has been reported.
