Dan,
   The 9 servers are operated by Chaum, and is the software and OS config
   open source and 3rd party verifiable as being the same as running on
   the servers?

   9 servers will be operated in 9 different jurisdictions, not by 9
   separate unrelated 'entities'.

   'Trust us' is just something we've become accustomed to not needing.

     With respect, the stripping involved requires unanimity amongst the
     nine sites, each much different than the other.  If one is to
     dismiss
     Chaum's scheme due to the possibility of 9-way unanimous collusion,
     then, in like manner, all threshold (split-key) cryptosystems are
     unacceptable.  And then there is the DNS where the possibility of
     collusion amongst all root servers would also trigger disavowal of
     the DNS.
     I'm probably missing your point.
