(Why would they move to the Tiny? ;-)

The idea of using the Shield is because it is a defined interface witj
several suppliers of ready made breadbords which should make it easy and
cheap (for others) to build the entropy source on. That doesn't mean one
has to use an Arduino. It is just a convient board standard that more
and more devices supports. The C5G for example.

And Arduino could probably use a good entropy source and RNG too. Also
note that the Arduino Due uses a much faster MCU (An ARM or in the older
version an AVR32). But I'm digressing here...

Otherwise it seems that we should be able to easily connect your design
to the C5G board.
