Agreed, re my experience with the use of IRLP and Echolink during 
hurricanes, and which should be largely applicable to D-STAR as 
well.  The most common failure mode seen in hurricane conditions is 
lack of power at the repeater site.  If there is power available, the 
Internet service usually fares better.

Nice.  I worked on something similar with IRLP, and have an IRLP node 
that will work on a 3G service. :)
