Now I'm sticking this in, and I found in the README
some comment about encryption - how they had ok encryption included, but you could download stuff to make it better. Then they send you off into bouncing from one design document to the other. Did anyone get a url for the better encryption download? It's certainly allowed here.
EDIT: jre1.7.0_7 actually sets up in a jre1.6.0_35/ directory :-/.
