My ultimate goal is to get the live data to  a bigger screen.  I can't justify upgrading to a new unit with video out, and it is fun to search and learn about new things anyway.  I see on the internet several folks wanted SD to UBS for mass storage of ipods, palms etc.  A company makes a chip to do it so it is getting closer.   Someone just needs to put it on a card and make an interface.   Saw the wireless and thought that might work.
