It was easy to cost justify the `blazer, non-standard and all, when
the older technology was 2400 and the blazer promised up to 18000.
Nobody gets that, of course, (I see around 12000 using AT&T into UUNET,
*much* less if I use SPRINT).  So lets take the published limits
and figure that real users will get 2/3 of what is claimed.  That
puts the 'blazer++ at around 18000 usable.  Only 50% more bandwidth.
That would probably mean that I couldn't justify upgrading FROM
a 'blazer+ to a 'blazer++ unless the price was dirt cheap (unlikely).
But the 'blazer++ would be very attractive to the 2400 baud holdouts.

So, you can see that there will be a large imbedded base that probably
won't switch based on savings alone.  And a group of converts that
will switch, but only *if the 'blazer++ can talk to the imbedded base*.
"Likely" isn't good enough.  It "must" talk to existing 'blazer+'s.
