Pete, this is what I meant by 'deliberately obtuse.'  Your response to 
most questions has been to refer everyone to other posts or papers that 
we've already read and clearly not completely understood - or to offer 
to discuss it off-list.  That's why I'm asking for some patience from 
you in helping us all understand.

There are clearly a lot of people here (myself included) that don't have 
an opportunity to use D-STAR, and don't know a lot about how it works. 
Most D-STAR users do NOT have intimate knowledge of how the data 
sub-channel works and how it might be applied, and I for one don't want 
to join a D-STAR group and sort through all of the misinformation to try 
to figure out if D-STAR is even something I want to mess with.  So 
again, if you want APRS users to seriously consider D-PRS, have a little 
patience and help us understand its capabilities and limitations.
