1) safer and fast version
   cat blob | ssh host > tmp;
   for var in ...
      var=grep ^var= tmp
2) slow & secure
   for var in ...
   eval var=$(cat single_blob | ssh host"

3) easy & insecure
   cat blob | ssh host > tmp; . tmp
   
4)   - rsync here/explorers target/explorers
   - ssh target_host for explorer in target/explorers/; do
      target/explorers/$explorer > target/cache/explorers/$explorer
     done
   - rsync target/cache/explorers here/cache/explorers....
   - MINUS RSYNC!!!!!!!!!??????????

TO_MAN: EXPLORER VALUES ARE UNTRUSTED (think of webclients and webapps)
