100ft of feedline would be pretty heavy... of course, so would 
batteries for any extended period of operation.

maybe that's another balloonsat experiment - see how long we can 
operate a digipeater with a set of lithiums, maybe with some solar 
backup.  Let's see, where did I put that digipeater code for a PIC?  (:

Deploying out of a sheltered highbay can get exciting if there's very 
much surface wind.  I don't know if you could manage to deploy in the 
woods if there was any wind at all.
