+* Split the sdcard into two partitions one smal wich contains the bootloader, kernel and initrd and an encrypted root filesystem.
+* Integrate Tor into initrd
+* calculate a hash with sensors wich messure the enviroment (pressure against a case, eg.)
+
+If the Pi hast power and a network conetcion ...
+
+ - it can calculate the hash
+ - start the tor client
+ - ask a specific hidden service with the hash for a key
+ - if the hash is korect it return the key wich unlook the rootfs
