The problem is that a number standing by itself without the kind of
definitional context Eric's questions are driving at just isn't very

For any given detailed ground segment definition, there are two numbers
that *are* interesting.  One is what the intended users would be willing
to pay for the defined functionality, the other is what "retail" price
we think we can deliver that defined functionality for.  If the former
exceeds the latter, then we have an instant hit.  If not, then we have
more work to do...  ;-)

Ok, so we now have a data point for what some users might be willing to
pay for a ground station, but without a crisp definition of what they
think they're getting for that price.  Fair?  Not a bad starting point.

I'm not sure I understand what you mean here?

I hope you understand, given what I said above, and your own comments
about multiple configurations, why I find these numbers completely
unsatisfying standing alone like this.

Crisp definitions of what's included in each "configuration" of a ground
station to "ground" the cost and price analysis would be a great place
to start.
