Hi Skip,

Dang service call broke into coffee time, but I did get to visit the 
local hams for a bit.  As far as I know the DSTAR user radios can be set 
to busy channel lock out, so they will not transmit when there is 
anything on the channel.  They also have an S Meter that will show 
activity, and can be set to monitor for analog or digital.

One down side would be the internet gateway.  I can direct a call to the 
DSTAR repeater in Malibu, CA from here in Temple, Texas  and have no 
idea whether the channel in Malibu had analog traffic or not.  Local 
folks could be observant, but folks thru the gateway would not know.  
This may be how folks contrive the DSTAR repeater to be an AUX Station 
because it can be caused to transmit by another station via the internet 
in another area.  This may be a secondary function, though, because 
primarily the repeater works as a repeater, and I would venture that 2/3 
of the DSTAR systems in the US are not connected to the internet.
