        and has the octuplet??
 
+- AAAGH We can't use 80-bit hashes inside the tree, and it's
+  questionable whether we can even use 160-bit! 
+  Reason: if you sign a lot of docs, chances are 
+  you get a common birthday: two instances
+  of the same key used at two different branches.
+
+  Especially since we use N primitive signatures for each sig.
+
+  This needs to be reasoned out carefully.
