First as has been discussed ad-nausium here is the fact that
switching to 9600 baud at the user only gains at most a 
factor of 2 gain due to the TX delays and other overhead,

If you are talking about Nodes, then yes, that is the whole
point.  The nodes have to feed to the combined feed at
9600. that is what the 9600 baud UHF backbones that
I have been talking about since Sept 2003 are all about.

But your example is not a one-to-all.  It is a point-to-point and has
10 megabyit bandwidth.   That is on another planet compared to
APRS one-to-all communications with 1200 baud radios.
