Hadn't seen that one - thanks for the link. I think it is good to see there 
are people working on other sources than avalanche noise.

There's also some interesting documentation on the site - like test output 
showing that they too "fail" to get a good chi square number from 'ent' with 
just raw avalanche noise data (here: 
http://moonbaseotago.com/onerng/theory.html).

I'm currently playing around with ways to avoid correlation in my output (if 
I've understood it correctly, that is what the chi square test picks up), 
although perhaps that is really a task for the mixer in the Cryptech.
