And of course, the propellant loading is not the same all the way through
the booster is it, so presumably, that will need to be done differently as
well.

No, we're not "saying" that, I'm asking that! :-)

I didn't think that the statement on the web site I linked to was clear
on
that detail.

Ultimately, what I am wondering is since it seems that an inline
five-segment SRB is going to be used for at least the heavy lift needs
post-shuttle, will there be some savings due to lots of
"flight-certified"
SRB segments available, without need to manufacture new ones? Or, will
these
SRBs cost the same as now? What will the "re-certification" (or whatever)
requirements be for refurbished boosters, given they would be used for
cargo
only (in this application)?

I didn't snip anything in your reply, Jon, because I agree with all of
it. These questions are key to determining how much any SDV will
actually end up costing. I'm also wondering if the 5-segment SRBs can
be stacked using current SRB segments or are loads, etc., sufficiently
different such that each 5-segment SRB must be constructed of segments
designed/built specifically for use in a 5-segment stack? That is
something else that would be good to know in this analysis. I'm sure
Lowther could tell us but since I've killfiled him due to anti-social
behavior, someone will have to let me know what he says. :-)
